hi, just installed sunvic TLX RFPv wireless thermostat in to my sime 90 plus boiler having a problem setting temperature,should i set the boiler temp to full and then let the thermostat take control or do i disconnect the thermostat in the boiler ? cause at the moment when boiler fires up rads get sooo hot until reached temp the go off is this how it should be? i thought i would have more control on the temp. if i turn the temp dial down on my boiler when the sunvic has swithed the heating on the boiler switches off.I assumed when you wire the transmitter to the boiler it would over ride the boilers thermostat.still trying to understand how it all works so any help would be greatly appreciated, cheers
