Remember the is a time and temperature controller if you want to use as an ON/OFF controller please ensure you OFF times are set to LOW temperatures for example at 8:00am I want the boiler firing to 21°C at 10:00 I want the boiler to go OFF at 5°C so ensure all so called OFF times are set to LOW temperatures.

Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.

Access the installer setup menu (You will need the installation manual from the t'stat to do this) and turn off the "intelligent recovery" feature. This feature turns the equipment on in order to bring the conditioned area up to temp at the set time. Or you could set the "wake time" to 6:50!!!
