BPS242RF Thermostat Auto Issues

[plugmypipe]

Have a thermostat (BPS242RF) and the receiver box on the wall (BR1 Boss Therm). Setting the thermostat as per the manual, but the auto setting seems to have a mind of its own and keeps turning the heating on when not required. For example. The thermostat clock is set to a 24hour clock. The thermostat set to come on at 10.30am and off at 11.15am, as I am testing. I leave the boiler on at night and the thermostat set to auto which is showing as 'off' which it should at night. I then checked the heating at night around 11.45pm and the heating is on and radiators hot. This shouldn't be happening until 10.30am in the morning. This keeps happening even when changing time settings.

Is this a regular problem with this model thermostat and setting it to auto ?

What are the switch on/off times?

What are the comfort/setback temperatures?

The switch on / off times are:-

A1 = 10.45am ON
A2 = 11.15am OFF
A3 = 16.00pm ON
A4 = 17.30pm OFF

The comfort / setback temperatures are:-

comfort 17
setback 18

Hope this helps

Are you certain that the setback temperature is higher than the comfort temperature? It's not normal to do that as the setback temperature is usually much lower than the comfort.

The times are, to say the least, very unusual. Heating on for half an hour in the morning and 90 minutes in the afternoon!

I would have expected settings similar to this:

A1 = 0700 - ON, 20C (Comfort)
A2 = 0900 - OFF, 10C (Setback)
A3 = 1700 - ON, 20C (Comfort)
A4 = 2230 - OFF, 10C (Setback)

Thanks for the reply.

The settings I set are just for testing, they aren't permanent. Could the setback and comfort temperatures be set at their lowest 5C ?

So basically, setting auto times is also dependent on comfort and setback temperatures, rather than being independent of them ?
