15. ERROR CODES
Er1: Internal error
Er2: Z-Wave error
Er3: Internal error
Er4: Floor sensor error
Er5: External sensor error
If you have chosen F or AF sensor mode without having a floor
sensor connected, Er4 will be shown in the display. If you have
chosen A2 or A2F, and there is no external sensors installed, Er5
will be shown in the display. If the Er1, Er2 or Er3 error codes are
shown, contact your local dealer or Thermo-Floor AS.
OPERATING THE DEVICE
Multi Channel support:
Heatit Z-TRM2 has support for the Multi Channel Command
Class, and can therefore be seen as many devices by the
Z-Wave Controller. Where each of the devices has association
groups in order to send information to other Z-Wave devices,
see the chapter concerning association groups.
The first Multilevel Sensor device is reporting the temperature
for the internal temperature sensor.
Second Multilevel Device reports the temperature for the
external temperature sensor.
Third Multilevel device reports the temperature for the floor
sensor.
Commands sent to each of the logical devices will be
interpreted according to the description in the section:
Supporting Command Classes.
No Multi Channel support:
If the Z-Wave Controller, or the Z-Wave devices that shall be
associated with Heatit, does not support the Multi Channel
Command Class (Multichannel encapsulation), then only the
association groups in the root device is accessible. This device
will contain 5 association groups. For further information, see
the chapter concerning association groups. The root device is
the actual thermostat device.
Supporting Command Classes:
Besides the mandatory command classes, Heatit has support for
following command classes:
• Basic Command Class.
Will send Basic Report information about the current status of
the built-in relay.
• Binary Switch Command Class.
Sends Binary Switch Set commands to other devices when the
internal relay is switched. It can be used to control other slave
relay devices.
• Thermostat Setpoint Command Class.
When a Thermostat Setpoint Set command is received by the
root device, it can set the actual setpoints for the three different
modes the thermostat is able to operate in; Setpoint for the
heating mode, setpoint for cooling mode and the setpoint for
energy saving mode.
• Thermostat Mode.
It is possible to change the operating mode of the thermostat
by sending a Thermostat Mode Set command. This way it is
possible to set the operating mode to: Heating Mode, Cooling
Mode or Energy Saving Mode.
Security:
Heatit Z-TRM2 is able to operate in security S0 and S2 mode, this
requires that the device is added in security mode during the
inclusion process.
NODE INFORMATION FRAME
The Node Information Frame is the business card of a Z-Wave
device. It contains information about the device type and the
technical capabilities. The inclusion and exclusion of the device
is confirmed by sending out a Node Information Frame. Beside
this, it may be necessary for certain network operations to send
out a Node Information Frame.
ASSOCIATIONS
Z-Wave devices control other Z-Wave devices. The relationship
between one device controlling another device is called
association. In order to control a different device, the controlling
device needs to maintain a list of devices that will receive
controlling commands. These lists are called association groups
and they are always related to certain events (e.g. sensor reports,
...). In case the event happens all devices stored in the respective
association group will receive a common wireless command.
