The batteries in my wireless thermostat have leaked and it is damaged beyond repair. Is there any way to turn the heating on without a thermostat. Boiler is an iqe simplicity 25. It has a salus wireless receiver wired into it. I tried buying a replacement thermostat but mustn't be compatible with the receiver. I don't know what model the receiver is as it fixed to the wall and probably says on the back what model it is.....clever.
