Sitatposter svar jeg fikk fra Pasi Alvemaa som er Technical Manager Wallas Finland:
Det skal i følge han gå an å styre Wallas via en 3 part enhet med rele styring.

Start and stop
The heater can be started by using remote control device which has a relay and its state can be controlled. The control panel needs to be plugged to a heater to get it work.
The command of the control panel "Start heater" is a digital input signal with an internal 10 kohm pull-up resistor to 5 volts.
To start the heater, pull this "Start heater" signal low to GND. To stop the heater, drive the "Start heater" high or release it.
Signal level is interpreted as low, if voltage in connector pin is 0.0 - 1.0 volts. If signal level is between 4.0 - 5.0 volts the signal is interpreted as high.
Signal state of the "Start heater" should be high and stable as long as the heater is wanted to be on.
Stopping heater is possible, even if the heater has been started from the control panel, by pressing a heater button. This is done by first pulling "Start heater" low (at least 5 seconds) and then releasing it.
Flame detection
"Flame detection" is a digital output signal with an output impedance of 1000 ohms.
When inactive, the signal is driven to a voltage level of 5.0 volts.
When active, the signal is driven to a voltage level of 0.45 volts
Note: "Flame detection" signal state is undefined if Relay interface is not explicitly in use by pulling "Start heater" low!

IMPORTANT NOTES!
Behavior of the device
When the pin 4 is wired to the pin 2, the heater will start to PI-thermo control (thermostatic) mode. Even if the heater has been used at the very last time in manual adjusting mode, the remote control startup will start the heater to PI-thermo control mode.
The control panel will indicate that the device is in remote control use, by blinking the orange thermostat light at the bottom left at following frequency: every tenth second, the orange thermostat light blinks 0.25 seconds. (0.25s/10s)
The sun switch is deactivated when using remote control.
If the heater has been started with remote control, it is impossible to shut down the heater from the control panel. When started via remote control, the pin 4 needs to drive high or release, to shut down the heater.
Dette gjelder for Wallass 40CC/26CC
