Boost Function on EPH Controls Thermostat

To be energy efficient please use the thermostat as instructed:

1. Leave on AUTO function. If the whole house is too hot or you do not want the heating on press "OFF" on the thermostat. Please do not turn the heating off at the boiler as this often results in low pressure on the boiler which will affect the heating and hot water when you want to turn it back on.  

2. If you cannot agree on a set temperature throughout the property leave on AUTO and turn down or off individual radiators.

3. If you wish for a higher temperature (up to a maximum of 23 degrees) please use the BOOST function for 1,2 or 3 hours at a time (refer to instructions below).

BOOST FUNCTION

The thermostat can be boosted up to a maximum of 23 degrees for 1, 2, or 3 hours at a time while the thermostat is operating in all modes except for holiday mode. We would recommend having the heating no higher than 20 degrees. 

Press the BOOST button 1, 2, or 3 times, the time that the boost will be activated to will flash on the screen.  

If you do not press any other button, the boost will activate to the temperature displayed on the screen after 5 seconds.  

If you press the OK button, the temperature will now flash. You can edit the temperature if you press the + or – buttons.  

Press the OK button or wait for 5 seconds for the boost to activate.  

BOOST TO will now be displayed on the screen with the time that it is activated to displayed above this text.  

Press the BOOST button again to deactivate the boost

The heating system has fixed on and fixed re-set points as set out in the table below. As these run concurrently, the heating is available to be on 24/7, the re-set point is not an off point – it’s the temperature  that the heating re-sets to at the listed time.

	P1	P2	P3	P4	P5	P6
Monday - Friday	6:30am	8:00am	12:00pm	2:00pm	5:30pm	10:00pm
	21	10	10	10	21	10
Saturday - Sunday	8:00am	10:00am	12:00pm	2:00pm	5:30pm	11:00pm
	21	10	10	10	21	10

The heating will come on automatically and stay on whilst the temperature of the room in which the thermostat is located falls below its baseline. Once the room exceeds the temperature the heating will go off. 

Boosts are event and time limited. Therefore the heating will then stay on until the first of the two below occur:
Either
The thermostat reaches your set temperature, then the heating will go off [event limited- temp reaches 23 degrees]
Or
A re set time occurs, at which point the baseline reverts to 10 (or 21) degrees [time limited- next re-set time]
