Specifications

The Spirit Zigbee (SPZB0001) is Eurotronic’s Zigbee version of its Spirit energy-saving radiator thermostat, made in Germany. It uses the Zigbee Home Automation Profile 1.2 as a heating device, and Eurotronic states that it can join any Zigbee network and work with Zigbee-certified devices from other manufacturers, with encrypted communication where the network supports it. It runs on two AA cells and takes firmware updates over the air.1

Where it is used

  • Room heating setpoints in offices, schools and guest rooms with wet radiators, with room temperature logged beside them.

    Indoor environmental monitoring

  • Heating control run from Edge on a separate room sensor, with the thermostat in manual valve mode as a simple actuator.

    HVAC energy monitoring for commercial buildings

  • Turning heating off in ventilated rooms, from the thermostat’s own window detection or a window contact.

trv_mode 2 is thermostat mode, the default. trv_mode 1 is manual valve mode: write valve_position from 0 (closed) to 255 (fully open). In manual mode the buttons are disabled and the display shows the valve position.2

system_mode heat sets the boost flag and off sets the window-open flag, which the display shows as OFF.2

The thermostat sends several identical messages in quick succession. A debounce of about 0.5 seconds removes the repeats.2

Error bits: E1 valve adaptation failed, E2 valve movement too slow, E3 valve not moving.1

Setup

  1. Open pairing in Edge

    Open pairing on the Gateway’s Zigbee network in Edge. The thermostat can only join while the network is accepting devices.1

  2. Insert the batteries

    Insert the batteries. The display shows PrP, then a flashing radio symbol: a new Spirit is in join mode from the factory. When it has joined, the radio symbol stays on and the Boost button flashes green. ERR means the join failed.1

  3. Mount it

    Press Boost. When the display shows INS, fit the adapter if the valve needs one and screw the thermostat onto the valve.1

  4. Adapt to the valve

    Press Boost again. ADA shows while it learns the valve, then the display shows the target temperature. ER1 means no valve was found; check the mounting and the adapter.1

  5. Check one reading

    Confirm that Edge identifies it as Eurotronic SPZB0001, then raise the setpoint from Edge and watch heating demand rise. Compare the room temperature with a reference thermometer.

Common questions

Can Edge set the valve position directly?
Yes. Set trv_mode to 1 and write valve_position from 0 (closed) to 255 (fully open). The thermostat stops regulating and its buttons are disabled until trv_mode goes back to 2.2
How do I reset it?
Hold Boost, plus and minus together until the counter on the display reaches 10, and release when RES appears. The display then shows PrP and the valve stem moves to the mounting position. Eurotronic advises a factory reset only when the old Zigbee controller no longer exists.1
What do ER1, ER2 and ER3 mean?
ER1: no valve detected. ER2: the closing point was not found. ER3: the valve cannot be positioned; check that the valve pin moves freely. Press Boost to clear the message.1
