The instruction on setting the temp span and day programme selection refer to pressing the RESET button after each DIP alteration. Is this the SET button on the front or is there another button?Thanks Answers 1
No, it is the small recessed button under the snowflake button. You will need a pin to press it.

Hello, I have the box that is connected to the boiler but not the thermostat control, can I expect the control to work with my current box or do they work on different frequencies? And as far as you know, could I just change it for another thermostat that's more modern (just by using the current wiring into a different thermostat) or does it not work that way? Answers 1
The receiver need to be compatible with the thermostat. If you have a HRFS1 receiver, then you can only use a HRFS1 thermostat.

Answers 1 Under the downloads tab.When I set My programmer (manually or timed) to off but my boiler will continue to stay on until the temperature on the Horstmann is reached ? Answers 1
It is likely the programmer has been overridden to avoid it clashing with the programmable thermostat. Programming must be done on the thermostat.
Can we get a replacement control unit? We’ve just moved home and the system seems to work on pre-set but the hand controls are broken. Answers 1
I'm afraid it is only available as a pair.We've recently had a new oil boiler installed and we have a problem with the thermostat. We have the day temp set at 22.5°C with a 0.5°C differential, so the boiler should come on at 22°C and knock off at 23°C, but it isn't knocking off until it reaches 25.5°C. I've tried moving the thermostat closer to the boiler but it doesn't make any difference. The batteries are new, I've reset and reprogrammed the thermostat but nothing seems to make a difference, could it be a problem with the boiler controls? Answers 1
Check to see what the thermostat thinks the ambient temperature is. Check to see if the symbol on the display matches the light on the receiver. Support is available on 01962 826213
