Hello all,

After installing our new steam boiler in a 4-story brownstone the heat isn’t reaching the top floor. I have Honeywell Pro TH4000 Series programmable but it isn’t ideal for a 4-story steam unit.

My situation:
1) The thermostat is on the 1st floor, shutting off too soon for sufficient pressure to build to reach 4thfloor. Of course the 1st floor warms faster and kicks it off.
2) I don’t want to replace the valves as they are in working order.
3) The unit ‘trickles’ heat all day, off & on, off & on, but only heats the bottom 2 floors, which is an inefficient waste of gas.
4) When the thermostat’s programmed ‘RETURN’ and ‘WAKE’ settings kick in, of course the temperature variance between the current and setting are significant enough to cause the boiler to run 30 minutes, reaching the 4th FL.

What I NEED:
I want a thermostat that can be programmed to cycle every 3 (winter) or 4 (fall/spring) hours. Meaning, it only checks the temp every 3 – 4 hours so that the temperature difference between the current and ‘setting’ is allowed to separate enough to run the boiler for 20 or 30 minutes, thereby reaching the 4th FL. This would easily save sufficient heating expense and appease those upstairs. Also, it would provide better heating as if the unit runs 20 –30 minutes ALL the pipes and radiators heat up, thereby sustaining warmer floors for longer periods of time.

Any recommendations on a programmable thermostat; model/make?

Thank you!
