varmo TZ Pro is a Z-Wave controlled electronic radiator thermostat. It is mounted on wall heating valves and controls them by a motor. The device accepts a setpoint that is either set manually using buttons on the device or wirelessly using Z-Wave. Afterwards, the device will regulate the warm water supply to the wall radiator and compare the detected temperature to ensure, that the temperature in the room is kept at the desired level. A small LCD panel on the device displays the setpoint temperature on request.
The device has an internal scheduler, that allows to define up to 9 setpoints for up to 7 week days. Once programmed, these setpoints will be activated without any further manual or wireless interaction. Beside setting a desired temperature the device will support, frost protection and intelligent functions like a valve training function to ensure that valves are still operational after longer periods.
The varmo TZ Pro can be mounted to valves with standard M30x1.5 connector or RA2000 (Danfoss snap in).
Installation
Adjustment to the radiatorThe device can be adjusted to the room size. Three room sizes are known. The factory setting is P2. Use P1 if the radiator appears oversized for the room. Use P3 if it is undersized. To change the assumed room size press (p) for 3 seconds to enter management mode (M in display). Press (v) until a "Pb" is displayed in the LCD display. Hit the (o) button. Now select 1, 2 or 3 using the arrow keys and exit with (o).
RemovalTo remove the thermostat, insert an appropriate tool in the hole in the thermostat"s battery chamber (see illustration). Keeping the tool in position, turn the entire thermostat anticlockwise until it is completely unscrewed.
The DONEXON device is operated by wireless commands from a Z-Wave controller. It is operated in two different modes:
The actual temperature setpoint is shown in the LCD display and can be overwritten by using the arrow keys on the device. This overwriting is temporary and only valid until the next change of the temperature setpoint either triggered from external wireless command.
The device will also recognize an open window (sudden temperature drop within short period of time) and turn down the heat for 30 minutes to save energy.
Local LCD DisplayThe local LCD display gives information about the status of the device
Link TestThe Thermostat allows to check the link quality to the controller device. Press the middle button (o) for 3 seconds until M is displayed. Select "LI" in display using the arrow keys, then confirm the link test with the middle button. A blinking antenna symbol indicates the link test. If the antenna symbol keeps flashing after about 3 seconds there is a problem with the wireless connection. If the antenna symbol stops flashing, the link quality is sufficient. A successfull link test will also terminate the exception mode described below.
The device applies multiple technologies to extend battery life. It is combining multi commands to a single command and adapt its behavior to the capabilities of the network controller. Make sure to use varmo TZ Pro only with Z-Wave controllers fully implementing all battery life time extention methods recommended by Danfoss.
When the battery level is low, the alarm bell icon flashes. If the battery goes flat, the system switches automatically to frost protection mode.++
Adjustment to the radiators and the room
The factory setting is P2. Use P1 if the radiator appears oversized for the room. Use P3 if it is undersized.*
- Press the middle button for at least 3 seconds until M is displayed.
- Press down (V) until Pb is displayed.
- Press the middle button
- Select P1, P2 or P3 using the arrow keys, and exit using the middler button
*The frequency of adjustment for P1, P2 and P3 varies to compensate for radiator over/under sizing.
Reset to factory default | Remove the battery cover and take out one battery. Press and hold the (o) button for about 10 secs while reinserting the battery. The device will go into management mode. |
Inclusion | Click on the middle button will confirm inclusion and wakeup the device for wireless communication. A long push for 3 seconds on the middle buttons enters and leaves the management mode indicated by a "M". |
Exclusion | Click on the middle button will confirm exclusion and wakeup the device for wireless communication. A long push for 3 seconds on the middle buttons enters and leaves the management mode indicated by a "M". |
NIF | Click on the middle button will send out a Node Information Frame (if not in exception mode). |
Wakeup | Click on the middle button will wakeup the device for wireless communication (if not in exception mode). |
