pump or dual-fuel equipment.

• Controls up to four zones and can be expanded up to

32 zones with Add-A-Zone Control Panels.

• Uses Honeywell four-wire, single-stage, multi-stage, or

select heat pump thermostats.

• Zone-A-Lone central setback feature.

INSTALLATION

Mounting

CAUTION

Equipment Damage Hazard.

Do not mount TZ-4 inside HVAC equipment

Mount only on wall or on cold air return.

Identifying DIP Switches

This panel has two banks of DIP switches, DIP switch 4 (S4)

and DIP switch 5 (S5), see Fig 15. Each bank has eight

individual switches that are identified by two numbers; the first

number is the bank number (4 or 5) and the second number

identifies the individual switch. For example, DIP 5-1 is bank

5, switch 1.

1. Mount the thermostats in each zone of the living space

using the installation instructions provided with each

thermostat.

2. Mount the dampers in the ductwork using the installa-

tion instructions provided with each damper.

3. Mount the TZ-4 zone panel near the HVAC equipment;

(on a wall or on the cold-air return). See Fig. 2.

4. Level the TZ-4 for appearance only.

Wiring

CAUTION

Voltage Hazard.

Can cause electrical shock or equipment damage.

Disconnect power before continuing installation.

Wiring must comply with applicable codes, ordinances, and

regulations.

1. Connect thermostats as shown in Fig. 3-6.

2. Connect dampers as shown in Fig. 7-10.

3. Connect C7735A Discharge Air Temperature Sensor

(not supplied) to the DATS terminals. The wires are not

polarized. See Fig. 13.

4. Connect Add-A-Zone panels (if used) to the AZ1 and

AZ2 terminals.

5. Connect the HVAC equipment to the EQUIP terminals

on the panel. See Fig. 15-21.

6. Connect a 40 VA, 24 volt transformer to R (hot) and C

(common). This must be a dedicated transformer and

each TAZ-4 board also requires a transformer. See Fig.

12.

7. The auxiliary 40 VA 24-volt transformer can be con-

nected to T1 and T2 if additional power for dampers is

required. This second transformer is not required; how-

ever, total power consumption of panel and damper is

limited to 40VA without it.

Wiring Diagrams (Fig. 3 and 4)

Conventional Thermostats

Conventional (RWYG) thermostats can be used to control

conventional, multi-stage, and heat pump equipment. If the

thermostat has a common terminal, it is wired to C on the

panel, see Fig. 3. A multi-stage thermostat is wired with the

second and third stage of heat to W2 and W3 on the panel

thermostat connections, and with the second stage of cooling

to Y2. Leave the zone O/B thermostat jumper on the TZ-4

disconnected. See Single and Multi-Stage Operation in the

Operation section for instructions on staging the TZ-4.

The PC8900 with the W8900A or W8900C can be used as a

zone thermostat. See Fig. 4 for hookup. This thermostat can

be used to control up to 2 heat and 2 cool stages of

conventional equipment. When used to control heat pump

equipment, the W8900A is recommended.

Connect a jumper on the W8900 from Rc to Rh as shown in

Fig. 4. Wire terminals R and C to a transformer. If the system

current draw is within specifications, the R and C on the

W8900 could alternately be connected to R and C on the

TZ-4. The PC8900/W8900 draws 5 VA.

Heat Pump Thermostats

Select a heat pump thermostat from Table 1. If the thermostat

selected has a separate Y1 and W1 wire, as shown in Fig. 5,

leave the zone O/B thermostat type jumper on the TZ-4

disconnected, and wire as shown in Fig. 5.

If the PC8900/W8900 /Thermostat is used in a heat pump

application, use the W8900A, not the W8900B, and wire as

shown in Fig. 4.

If the thermostat selected from Table 1has a single Y terminal

for first stage heat and cool, wire as shown in Fig. 6. Wire

either O or B (not both) from the thermostat to the O/B

terminal on the panel. Locate the O/B thermostat jumper on

the TZ-4 near each zone thermostat wiring terminal. Connect

the jumper if O was used or leave disconnected if B was used.

Connect second stage, auxiliary heat to W2.

When using two- or three-stage heat pump thermostats with

single Y first-stage hookup, place a jumper from W2 to Y2 on

the TZ-4 thermostat connections. See Fig. 7.

See Single and Multi-Stage Operation in the Operation

section for instructions on staging the TZ-4.

ARD or ZD Dampers

Wire the ARD or ZD Damper to the panel as shown in Fig. 8.

Multiple dampers can be wired in parallel. Use these dampers

on systems up to 2000 cfm.

AOBD Dampers

Wire the AOBD dampers to the panel as shown in Fig. 9. Two

AOBD can be wired in tandem as shown in Fig. 10. More than

two AOBD dampers require the Slave Damper Control Relay

(SDCR).

dampers can be wired in parallel.

The ML6161 Motor causes the damper LED to illuminate

green constantly. WIre a relay as shown in Fig. 12 to restore

damper position indication.

Transformer

1. Wire the transformers to the panel as shown in Fig. 13.

One 40 VA, 24 Vac transformer controls up to five ARD

or ZD dampers.

2. Connect the transformer to terminals R and C.

3. Add the auxiliary transformer if six to ten ARD or ZD

dampers are used.

a. Wire auxiliary transformer to terminals T1 and T2.

b. It is important that these two transformers be wired

in phase. If they are wired out of phase, the internal

circuit breaker trips and the board de-powers. If this

occurs, remove power, correct the wiring and

restore power to the board.

IMPORTANT

If more than five dampers are required for one zone

or if more than ten dampers are used for the TZ-4,

use the Slave Damper Control Relay (SDCR).

Fig. 13. Wiring transformer(s) to panel.

Discharge Air and Outdoor Temperature Sensors

Wire the C7735A Discharge Air Temperature Sensor (DATS)

to the panel as shown in Fig. 14. The Purge LED (yellow)

flashes in all modes except purge if no DATS is connected to

the TZ-4 or if there is a problem with the DATS or the wiring.

For dual fuel applications, connect the C7089 Outdoor

Temperature Sensor as shown in Fig. 14.

Add-A-Zone Panel

Remove power from TZ-4 before connecting AZ-1 and AZ-2.

Wire the Add-A-Zone (TAZ-4) Panel to the TotalZone (TZ-4)

Panel as shown in Fig.15. Up to seven TAZ-4 Panels can be

wired to one TZ-4 panel to control up to 32 zones.

with a call for heat.

Hydro-Air: Wire the zone valve or circulator relay to the Rh

and W1 equipment terminals. (If the circulator relay has

powered terminals, remove the Rh Rc jumper.) Set DIP switch

5-6 to off to energize the fan with a call for heat.

Oil Heat: Wire the oil primary T, T terminals to the Rh and W

equipment terminals. (If the oil primary has powered

terminals, remove the Rh Rc jumper.)

Multi-Stage: Wire the equipment as shown in Fig. 16 using the

W2 and W3 terminals for second and third stages of heat.

Wire Y2 for second stage of cooling.
