Hi
I have an underfloor heating system where the hot water is supplied by an oil fired boiler.
The underfloor heating manifolds are controlled via an older design of the DT200 Honeywell room stats. The system works fine.
I would like to change these to DT90E Honeywell room stats.
I note that the DT90E is a TPI design where as the DT200 is a simple on / off.
I have read that the DT90E should be set up with a Min On/Off time of 4 minutes and a cycle rate of 3 cycles per hour when used with an oil fired boiler.
I understand that the DT90E is a direct replacement for the DT200.
I have it in my head that the boiler will be switched on and off for 4 minutes 3 times per hour.
I know that this is wrong, but will the underfloor heating system, which operates through thermal actuators, still work the same way as it does with the DT200s ?
Many thanks.
