Hello David, I don't know if you installed this thermostsat or had someone else to install it. If you don't have the manual for your DT92E thermostat, I found a PDF file online that coveres both DT92A and DT92A. If you scoll down the PDF file after opening it, towards the bottom, you will see how to adjust the boiler timing. Maybe the timing is still in default mode and needs to be adjusted for a longer burn time? Hope this helps out.
Probably not. There are replacement models available.
The T6661B programmable room thermostat is also known as CM61.
CM61 1 day wireless programmable thermostat is replaced by CM921.
CM61 1 day wired programmable thermostat is replaced by CM901.
All thermostat is calibrated @ difference of 2 degree.to cut in and cut off. In heat mode, if you keep 25 and your room temp 23. it will start at the end of 24 or beginning of 25 degree.Cut off also @27 degree beginning. Please check Tips & how to do's in Fixya
This Honeywell control thermostat is made for wireless control, by means of a relay control transmitter with a range of 30 meters. It only needs a 2 wire connection on this stat if indeed it is the DT92E stat. Even though the diagram shows three, you will need only 2 for operation. This is a fact. I have done some reading on this model and many of its relatives, so with built in relays, and transmitters, this is an amazing set-up. Good luck with it as you should enjoy its operation and user friendly features. Sincerely, Shastalaker7 A/C, Heating, & Refrigeration Contractor Please be kind when rating, as I know you will be.

I have a Siemens "Radio" Room Stat - the receiver has switched itself off. How do I restart it. I have pressed the restart button and the reset - nothing happens except for red light flashing and then off. I do not have the instructions. Where might I get them?
