Don't understand how to use thermostat

[Yumchips]

Sorry this will sound stupid but here goes. We have a Worcester combi boiler. Have just gotten a new thermostat installed. It is the Drayton digitstat with optional wireless control. It's a nightmare and house is always cold, it's never responding to the schedule I set. I'm about to take it back but wondered if there's any obvious things I'm missing. Also, I'm not sure what setting the boiler should be on - is the mechanical timer setting or just the 'on' setting? Does it make a difference? The water also doesn't feel as hot as usual. Is there a way to remedy this on the Worcester? Thank you!

You'll want the boiler set to on, if the thermostat has been installed as it should be. So, rather than having a schedule, the boiler comes on when the temperature drops below the set temperature.

You need to 'balance' the system so that the whole house heats up evenly. So, if the thermostat is right next to first radiator on the system, that area could reach whatever temperature yiu set, before the house has warmed up, and the thermostat then switches off.

The basic way of balancing is to open up all the TRV valves on every room you use, turn the heating on and monitor the temperature in each room, and then turn down the valve on the other end of the radiator in the rooms that are getting hotter quicker

You can pay someone to do this for you.

Thank you for your response, much appreciated. I didn't realise the location of the thermostat makes a difference. Mine is left in the kitchen next to the boiler but there's currently an extension taking place. It's cold in there but the heating doesn't seem to be on. I'm guessing I need to set the scheduler on the timer to a higher temperature? The balancing valve part makes sense to me., Thank you

Have you got an app that you control it from? I have a Hive and it has 3 settings - manual, schedule and off.
Manual just switches the heating on if it's below the temperature specified.
Schedule is to time the heating to come on and off at specific times and heat to the temperature you set. So if you've got it timed but only got the temperature set to lower than the temperature in the room then it's not going to bring the heating on.

I have given up trying to figure out mine. It wanted me to set the heat for each individual hour. And it randomly came on during the summer. It’s a fancy one too. I now just have it so I can turn it on and off.
but yes. I keep mine in the coldest room as it does make a difference
