HEATIT

Z-TRM3

Installers manual

Heatit Z-TRM3 is an electronic thermostat for electrical ﬂoor heating,

designed to be mounted in a standard ﬂush box. The thermostat has

a built-in Z-Wave chip that can be connected with Home Automation

systems. Heatit Z-TRM3 is equipped with a single-pole relay and ﬁts

into System 55 frames. The thermostat can withstand a load of max

16A /3600W at 230VAC.

Firmware 4.0

01.01.2021

Ver 2021-B (15.10.21)

NB! If the sensor mode is changed to A or AF mode then a room

sensor compensation process will start, which limits maximum power

output to 75%. The thermostat adapts to the environment within a

few days. No internal sensor calibration should be performed during

the ﬁrst few days.

Principles of regulation

Programming thermostat

The device needs to be added to an existing network to communicate

with the other devices within it. Devices may also be removed from

a network. The add/remove processes are initiated by the primary

controller of the Z-Wave network.

What do the operation mode numbers mean on the Heatit Z-TRM3?

Mode 0 is Off. Mode 1 is Heating mode. Modes 2 and 3 are sensor modes: F-mode uses floor sensor only, A-mode uses internal room sensor, AF-mode uses internal room sensor with floor limitation, and A2F-mode uses external sensor with floor limitation. Instruction Manual, p. 5

How do I set the heating mode setpoint temperature on the Heatit Z-TRM3?

Adjust parameter 9 (Heating mode setpoint) to a value between 50 and 400, where 50 equals 5.0°C and 400 equals 40.0°C. Default is 210 (21.0°C). Instruction Manual, p. 5

What do the sensor type codes mean on the Heatit Z-TRM3?

Parameter 2 selects the floor sensor type. Value 0 is 10K NTC (default), 1 is 12K NTC, 2 is 15K NTC, 3 is 22K NTC, 4 is 33K NTC, and 5 is 47K NTC. Instruction Manual, p. 5

What does the temperature display setting do on the Heatit Z-TRM3?

Parameter 13 (Temp. display) selects what appears on the display. Value 0 shows setpoint temperature (default), and value 1 shows measured temperature. Instruction Manual, p. 5

Can the Heatit Z-TRM3 operate in both security and non-security Z-Wave modes?

Yes. Set your primary controller in add mode for either security or non-security, then add the thermostat accordingly. Instruction Manual, p. 1

How do I know when the Heatit Z-TRM3 has been added to the Z-Wave network?

The display shows 'INC' when the thermostat is successfully added. Instruction Manual, p. 1

What's the maximum electrical load the Heatit Z-TRM3 can handle?
