Removing an existing thermostat

1. Disconnect the power to the control transformer.

2. Remove the cover to the existing thermostat.

3. Disconnect the wires going to each terminal on the thermostat. Label each wire with the letter or number

at the terminal.

4. Remove the existing plate or base from the wall.

MOUNTING

When mounting the RC-100BZ, grasp the thermostat by the sides, avoiding the keys, and unsnap the base from

the face.

Holding the base to the wall so that the word "TOP" is upright and facing you:

1. Mark the two mounting holes on the wall using a pencil.

2. Drill a hole using a 3/16" bit at each mounting hole marking.

3. Install the two wall anchors supplied.

4. Slide the system wires through the opening in the base.

5. Mount the base to the wall using the two #6 x 1/2" self-tapping screws supplied - See Figure 1.

Figure 1

Connect each wire to the terminal strip on the thermostat base per the wiring diagram for your system

application - See Figures 4 - 5.

Form the thermostat wiring so that the cable lies flat between the terminal strip and the center of the base.

Upon completion of wiring the thermostat, push all excess wiring into the hole in the wall. Plug the hole with

the supplied insulating foam to ensure an accurate temperature reading by the thermostat.

Align the tabs of the thermostat face with the slots of the thermostat base. Gently push the thermostat face into

the thermostat base locking it into place - See Figure 2.

Figure 2 Figure 3

Note:

Be sure that the thermostat temperature sensor is standing up, and that it has not been damaged during

installation - See Figure 3.

TYPICAL WIRING DIAGRAMS

CAUTION:

Be sure to disconnect the power to the control transformer before removing or installing thermostat.

Do not short compressor relay, fan relay, auxiliary heat relay, or reversing valve...even momentarily. This will

blow a non-replaceable fuse.

Do not attempt to hook up to live circuits. An accidental connection to a component on the thermostat circuit

board could cause damage to the thermostat.

NOTES

1) As a convenience to the installer, the compressor start up protection delay can be canceled. To cancel the

delay, press the Prog key 3 times, then press the Fan key 2 times.

2) "O" Terminal is energized for cooling

"B" Terminal is energized for heating

In most applications, the reversing valve is energized for cooling and should be connected to the "O"

terminal. If the heat pump requires the reversing valve to be energized for heating, connect the reversing

valve to the "B" terminal.

3) "X1" and "X2" are connected to a 24VAC Red LED, most often used to indicate a fault with the heat

pump compressor.

4) The Emergency Heat Relay (E Terminal) and outdoor thermostats (usually accessories to a heat pump),

are not used. The RC-100BZ automatically controls auxiliary heat efficiently.

The RC-100BZ requires at least 1 stage of auxiliary heat enabled at all times. If the heat pump is

equipped with an outdoor thermostat, it should be removed from the auxiliary heat circuit, or reconfigured

so that it can only disable 2nd and 3rd stage of auxiliary heat.

CONFIGURING THE BACKLIGHT ON THE RC-100BZ

The backlight on the RC-100BZ can be configured to one of three different modes: 1) on for 30 seconds when a

key is pressed, 2) always on, or 3) always off.

1) To configure the display backlight to turn on when a key is pressed, then back off 30 seconds later, set

the “JP2” (Select Backlight Mode) jumper to the “TIMED” position (between the top and middle pin on

the connector) - See Figure 6.

2) To configure the display backlight to always be on, set the “JP2” (Select Backlight Mode) jumper to the

“ON” position (between the middle and bottom pin on the connector) - See Figure 6.

3) To configure the display backlight to never come on (always off), remove the “JP2” (Select Backlight

Mode) jumper from the connector - See Figure 6.

DISABLE KEYS

The keys on the thermostat can be disabled to prevent anyone from controlling the thermostat locally. To

disable the keys, solder a wire jumper across “JP1” (two holes on the circuit board) - See Figure 6.

POWER UP

1. Double check wiring, be sure that there are no stray wires or wire strands at the connections.

2. Connect power to the transformer and system. The display will show all segments for about 5 seconds.

3. Press the Fan key. The fan should come on. Press the Fan key again. The fan should go off.

4. Set the Mode to "HEAT". Use the up arrow key to raise the desired temperature setting above the current

temperature. Ensure that the heat pump comes on, in heating mode. After a few minutes, set the mode to

"EM HEAT". The heat pump should stop and the auxiliary heating should come on. Set the mode to

OFF. Ensure that both the heat pump and auxiliary heat go off.

5. Set the Mode to "COOL". Use the down arrow key to lower the desired temperature setting below the

current temperature. Ensure that the heat pump comes on, in cooling mode. Set the mode to "OFF".

Ensure that the cooling unit goes off.

If the thermostat or system does not perform as stated above, recheck all wiring - See Troubleshooting Tips.

INSTALLER SETUP

This section describes the items that the installer must setup as part of the thermostat installation. The Installer

Setup mode is used to configure the general operating parameters of the thermostat.

When in Installer Setup mode:

1. The small digits on the top of the display are the item number.

2. The large blinking digits in the center of the display are the value of the item number.

3. Press the Prog (>) key to advance to the next item.

4. Press the Hold (<) key to return to the previous item.

5. Use the arrow keys (∧−∨) to change the value of each item.

6. Do not set the values to anything other than the specified range for each item.

7. To exit Setup mode, press the Fan key.

The thermostat will automatically exit Setup mode after 20 seconds of no key activity.

To enter the Installer Setup mode, press the Prog key three times (day will flash), then press the Fan key.

The word "default" indicates the initial setting when the thermostat is delivered from the factory.

00 Address

If you are using Communications Mode 0 or 1, and you are installing more than one thermostat, each must be

set to a consecutive address, starting at 1. The default address setting is 1.

An address from 1- 127 may be selected.

01 Communications mode

The thermostat can communicate with remote systems in 4 different modes. These modes are:

0 300 baud, RS-232 mode (for use with personal computers)

1 100 baud, Z-Wave mode (OmniLT, Omni, Omni II, OmniPro, and OmniPro II systems)

8 PESM mode, (use with Model 1503 automation systems)

24 Day/Night mode (for use with remote setback switch)

The default setting is 1.

02 System options

The thermostat can be configured with the following system options:

WITH NO

EEC EEC*

0 8 Auto changeover no fan with heat

1 9 Auto changeover fan on with heat

4 12 Manual changeover no fan with heat

5 13 Manual changeover fan on with heat

* Energy Efficient Control (EEC) of Auxiliary Heat: Select 0, 1, 4, and 5 to enable EEC, or 8, 9, 12, and 13 to

disable EEC display. See Owner's Manual for description of EEC.

The default setting is 1.

In most heat pump installations, the auxiliary heat is electric resistance heat and the Energy Efficient Control

(EEC) should be turned on (settings 0, 1, 4, and 5). If the heat pump is equipped with a more efficient auxiliary

heat, such as hot water supplied by a gas water heater, you may want to turn EEC off (settings 8, 9, 12, and 13).

The thermostat will act like a conventional 2 stage thermostat.

03 Display options

The thermostat can be configured to display the following attributes:

0 Celsius am/pm time format programmable

1 Fahrenheit am/pm time format programmable

2 Celsius 24-hour time format programmable

3 Fahrenheit 24-hour time format programmable

4 Celsius am/pm time format non-programmable

5 Fahrenheit am/pm time format non-programmable

6 Celsius 24-hour time format non-programmable

7 Fahrenheit 24-hour time format non-programmable

When communicating with an HAI controller, the thermostat should be configured as "non-programmable". To

disable the clock and filter reminder displays, add “16” to each value.

The default setting is 1.

04 Calibration offset

This item is used to raise or lower the current temperature reading by 1 degree Fahrenheit or 1/2 degree Celsius.

If this item is set to 30, no change will be made. Each digit below 30 will lower to temperature, and each digit

above 30 will raise the temperature.

(1 = “- 29” to 59 = “+ 29” temperature units; 30 = No change)

The default setting is 30.

05 Cool setpoint limit

This item is used to limit the temperature setting in cool mode. The desired cool setting can never be set below

this setting.

The default setting is 51.

06 Heat setpoint limit

This item is used to limit the temperature setting in heat mode. The desired heat setting can never be set above

this setting.

The default setting is 91.

07 Not used

08 Not used

09 Not used

10 Not used

11 Cooling minimum on/off time (minutes)

This item is used to limit the on and off times of the cooling system. When the cooling system starts, it must

remain on for the minimum time set by this item. When the cooling system turns off, it must remain off for a

minimum time set by this item.

Setting Cycles per hour (maximum)

5 6

6 5

7 4

8 3.7

10 3

The recommended setting is 8 minutes. A higher setting may be appropriate for buildings with low heat

loss/gain.

The default setting is 8.

12 Heating minimum on/off time (minutes)

This item is the same as the “Cooling minimum on/off time”, but for the heating system.

The default setting is 8.

13 Stage 2 Differential

This item specifies the temperature difference between stage 1 heating (the heat pump) and stage 2 heating

(auxiliary heat). The default setting of 2 (degrees F) is recommended for all applications. In special cases a

setting of 3 or 4 may be used when precise control of temperature is not as important as highest energy

efficiency, however, the thermostat will not be able to maintain temperature within 1 degree of its setting under

cold weather conditions. A setting of 1 or 0 is not recommended.

In this thermostat, the automatic anticipator will compensate for the temperature "droop" caused by the stage 2

differential under cold weather conditions.

14 Clock adjust

If the clock on the thermostat is running faster or slower than the actual time, you can have the thermostat

automatically compensate up to 29 seconds per day. The thermostat will add or subtract the selected amount of

time daily.

(1 = “- 29” to 59 = “+ 29” seconds per day; 30 = No change)

The default setting is 30.

Note: If an HAI automation system is being used, the controller system time is sent to the thermostat every

minute. This adjustment will have no effect.
