Heatslave 15/19 thermostat

[Mechanicdan]

Hi I’ve got a Worcester 15/19 I have been given a new Navien wireless thermostat by a friend. But the wiring on the end of the receiver has a 2 wire plug. But the control board has block to tighten wires too. Can I just snip the plug off and connect the wires. Or is it just not compatible thanks Dan

Having a skim through the manual, it seems it’s best suited to a Navien boiler, as that cable is a communication cable, so might be similar to Vaillant/Glowworm ebus.

The installation manual stipulates that 230 volt must be kept away from the receiver, so it would likely not be compatible with the Heatslave. The thermostat connections need to switch the relasys on the PCB, which require 230v
