Heatit Controls HEATIT Z-TRM3 User guide

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.

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.

8. PRINCIPLES OF REGULATION8. 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.

20. ZWAVE QRCODE / DSK
The QR-Code is needed when including a device using S2 security or
SmartStart. The Z-Wave DSK can be found in the QR-Code which is
located in 3 locations:
1. On the product box.
2. On the physical product, placed on the black plastic underneath
the front.
3. On the PCB internally.
21. SECURITY
S2 security enhances Z-Wave Plus with an additional layer of AES 128-bit
encryption of the wireless Z-Wave communication to prevent hacking
and man-in-middle attacks on the home network. This device supports
S2 and has a Z-Wave DSK QR-Code label that may be used when the
module is added to the Z-Wave home network. The primary controller will
ask for a 5-digit code, which can be found underneath the QR-Code.The
primary controller will then ask you to confirm the rest of the code that is
contained in the QR-Code.
22. NODE INFORMATION FRAME
The node information frame is the ”business card”of a Z-Wave device.
It contains information about the device type and its technical features.
The add and remove procedure of the device is confirmed by sending
out a node information frame. Besides this, it may be necessary for certain
network operations to send out a node information frame.
23. ASSOCIATIONS
Z-Wave devices interact with other Z-Wave devices. The relationship
between one device controlling another device is called an association.
In order to control a subordinate device, the controlling device needs to
maintain a list of devices that will receive controlling commands. These
lists are called ”Association Groups”. They are always related to the specific
event triggered (e.g., sensor reports). In case the event is triggered, all
devices stored in the respective association group will receive a joint
wireless command.
SETTING AND REMOVING ASSOCIATIONS
Associations may be assigned and removed via Z-Wave commands.
Please refer to your primary controller/Z-Wave gateway for more
information.
