1. INTRODUCTION

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 230V. The thermostat may be used for water based

heating if the thermostat is linked to the Heatit Z-Water.

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.

Metering, the load needs to be connected to both heating L + N.

NOTE! The top cover has to be installed when the thermostat is

connected to the main power source. The thermostat is not a SELV

product. All voltage parts must be considered to be 230VAC.

6. ADD/REMOVE

The primary controller/gateway has a mode for adding or removing

devices. Please refer to your primary controller manual on how to set the

primary controller in add/remove mode. The device may only be added

or removed from the network if the primary controller is in add/remove

mode. When the device is removed from the network, it will NOT revert to

factory settings.

There are two ways to add the Heatit Z-TRM3 to a Z-Wave network.

6.1 METHOD 1: STANDARD (MANUAL)

1. Press Center (conﬁrm) for 10 seconds. The display will show OFF.

2. Press Right (down) 5 times until you see Con on the display.

3. Start the add/remove device process in your primary controller.

4. Start the add/remove mode in the Heatit Z-TRM3 by pressing

Center (conﬁrm) for approximately 2 seconds.

Adding/removing mode is indicated on the display by rotating

LED segments on the display. This lasts until the timeout occurs

after 90 seconds, or until the module has been added/removed

in the network. Conﬁrmation will show Inc/EcL on the display. Exit

programming mode by choosing ESC in the menu. Your thermostat

is now ready for use with default settings.

NB! When the thermostat is removed from the gateway, the

parameters are not reset. To reset the parameters, see Chapter 7:

”Factory reset”. If adding/removing fails, Err (error) will appear.

Please perform a ”remove device” process and try again. If Err displays

again, please see Chapter 7: “Factory reset”.

6.2 METHOD 2: SMARTSTART (AUTOMATIC)

SmartStart enabled products can be added into a Z-Wave network

by scanning the Z-Wave QR-Code present on the product with a

controller providing SmartStart inclusion. No further action is required

and the SmartStart product will be added automatically within 10

minutes of being switched on in the network vicinity.

The Z-Wave QR-Code locations may be found in Chapter 20

”Z-Wave QR-Code/DSK”.

7. FACTORY RESET

By pressing buttons Right and Center (down and conﬁrm) for 20 seconds,

the thermostat will perform a complete factory reset.

NB! Please use this procedure only when the primary controller/ gateway

is missing or otherwise inoperable.

The device will display rES for 10 seconds while performing a factory reset.

When rES no longer is displayed, the thermostat has been reset.

7.1 STARTUP

AFTER POWERING UP THE THERMOSTAT FOR THE FIRST TIME, ALL

PARAMETERS WILL HAVE DEFAULT SETTINGS.

PRINCIPLES OF REGULA

PRINCIPLES OF REGULATION

TION

TION8. PRINCIPLES OF REGULATION

Using Floor / External sensor (F, A2 or A2F-Mode)

The thermostat uses temperature readings retrieved from the internal

sensor or external wired sensor to regulate heating. When you have

chosen a setpoint temperature, the thermostat will use an internal

hysteresis to regulate the temperature. This hysteresis is adjustable.

See Chapter 5 “Installation”.

Using Internal sensor (A-mode/AF mode)

If you have a set point of 20°C, the thermostat will use the full power until

the temperature is 19°C. The thermostat will then begin to regulate the

output from 19°C with a 75% duty cycle until it reaches 19,25°C. When

the temperature has reached 19.5°C the thermostat will use a 50% duty

cycle, until it reaches 20°C, then the thermostat turns oﬀ and repeats the

process. For example, at a 75% duty cycle it will turn ON for a total of 90

minutes and OFF for 30 minutes.

9. PROGRAMMING THE THERMOSTAT

To activate the programming mode, press Center (conﬁrm) for 10

seconds. The display will show OFF. You are now in programming

mode. To scroll up and down in the menu, use buttons 1 and 3 (left

and right) to navigate. To enter the submenu, press Center (conﬁrm).

Always conﬁrm your setting by pressing Center (conﬁrm) for

2 seconds. Sto will appear to indicate saved settings.

10. TEMPERATURE SHOWN IN DISPLAY

By default, the temperature shown on the display is the setpoint. This may

be altered with parameter 13: “Temperature display”. You may calibrate

the sensor values ±4 degrees using parameters 10 to 12.

11. STANDBY AND MAIN SCREEN

When the thermostat remains untouched for a while, it will automatically

revert to the standby screen. The standby screen will by default show

the setpoint temperature. By pressing any button once, you will see the

measured temperature. By pressing the left or right (up or down) button

one more time, you will change the setpoint.

to limit the ﬂoor temperature to a maximum of 27°C (in accordance with

speciﬁcations from most wooden ﬂoor manufacturers).

When using the thermostat is used in (AF or A2F) the ﬂoor limiter FHI is

automaticly set to 27°C. When using any other sensor type (A, F or A2F)

the max temperatures is default 5°C minum and 40°C maximum.
