Product Q&A
14 QuestionsQ: I have been using this product for few days. I want to ask that yesterday I left for work and set the temp on 68 by setting it to 68 degrees n pressing hold. When I came home, the temp was showing 72 degrees but as soon as I touch arrows keys, it showed me 68 degrees set. So my question is even though the temp is set on 68... Its showing 72 cause that's the room temp or the thermostat is defective.

A few years ago when I was renovating my home I purchased a few of these thermostats. Overall I was disappointed with their quality and performance. One was defective and Pex Supply quickly replaced it for me. As for performance I had a similar problem in that the thermostat did not regulate the room temperature accurately. There is one setting I suggest you try. Check your installation instructions, if I recall correctly (it’s been a few years) there is a setting for different types of heating systems, hot water steam, furnace, etc. (BTW, these thermostats don’t work on radiant floor heat!) I tried each setting until I found the one that worked best for my environment. In time I plan to replace these thermostats with better ones. These are inexpensive thermostats, but you know the old expression, you get what you pay for. Good luck.
Hi Muhammad. Try to calibrate the room temperature on the unit if possible. It operates like any thermometer where it can be adjusted upward or downward to display the correct temperature. In your case, you would want to calibrate downward 3 degrees so that your current 72 degrees displays 68 degrees.
Q: My current thermostat is for a baseboard heat and uses terminals W and RH. Will this unit work for this wire connection?
Asked by newbie 14 years ago
Add your answer
Yes it will work. You will need to use a battery for power.
Yes This worked with my hot water baseboard system with W & RH low voltage wires.
My current thermostat is for a baseboard heat and uses terminals W and RH. Will this unit work for this wire connection? YES. I replaced the non-programmable thermostats (Honeywell #t87k1007 Heat Only Thermostat) in two (2) zones with these. The wire connections I used were Red and White.
I have a baseboard boiler 24V system and bought this same thermostat. I hooked it up how I thought, but it didn't work so I called Honeywell and they had great tech support which helped me wire it to work for my system. I'm almost certian they could tell you how to wire this for any system as long as the voltage is correct. Previously I had a simple mercury thermostat. Only thing is I have to use batteries now....I had hoped to power the thermostat from the 24V, but that didn't work. Batteries last about a year though. I was also able to get a credit on my heating bill for installing programmable thermostats, and the credit was more than the cost of the thermostats.. Check with your local utility. Hope this helps.
Q: Can this be used with a heat pump system?
Asked by momof7marks 14 years ago
Add your answer
Verified Reply- PexSupply StaffYes, as long as the heat pump does not have auxiliary heat.
The user manual shows hook-up diagrams for heat pumps, among other configurations. Operation with some particular heat pump can only be inferred from this. The customer is advised to download a copy of the user manual from Venstar's web site.
Yes, I have the same model T-stat and have combination condenser/heat pumps, it's all in the wiring.
Yes, as long as you are only controlling one zone of heating and cooling.
Q: what is the rh an rc mean on the wiring on the unit
Asked by greg 14 years ago
Add your answer
Verified Reply- PexSupply StaffGenerally, RH is for heating and RC is for cooling.
Q: will this work with a boiler and baseboards
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffYes, it will.
The basic answer is yes but there are circumstances. If you are looking to replace a non programmable T-stat probably yes. You need to connect the two T terminals of the boiler control to this device according to the schematic with the thermostat. In most cases it should be the R and W terminals.
