I have a Digistat +2RF/+3RF wireless thermostat and SCR (pictured below) connected to a Saunier Duval Semia Condens F24 E boiler.
This morning, the receiver (SCR) malfunctioned out of the blue. No lights are lit on it and cutting the power and restoring it makes no difference.
In similar questions posted here and elsewhere, the suggested solution seems to be, "Buy a new wireless thermostat and SCR receiver combo."
They're about £90 as a set, though, so is it difficult to remove the cable linking the Digistat SCR to the boiler's circuit board, and hence return to the boiler's own internal controls?
If I remove the SCR cable, will the boiler return to internal control automatically, or must a new link be made internally somewhere, perhaps by re-connecting something that was disconnected when the SCR cable was first installed?
Hot water works fine btw. It's just the heating that is affected.
Thank you.
