GQuack Posted August 24, 2017 Posted August 24, 2017 I purchased a 2441TH some time ago in anticipation of using it for a new house build. We ended up going a different direction but I am thinking I can still use this thermostat for another purpose. I have a closet containing a bunch of equipment most of it enclosed in a rack which has a built in fan cooling system. I've got the fans plugged into an outletlinc so the fans can be turned off and on independently. I'd like to use the thermostat to keep track of the ambient temperature inside the closet and if it reaches a set point to kick off the fan. Seems doable.... A couple of things for me to figure out. 1) thermostat requires 24VAC so that can be solved easily with a 110V to 24V converter. The question I am pondering, aside from power, are there any other connections that need to be made? I don't know if the thermostat is dual-band but does it send Insteon commands via the 24V power line or through other connections? Many thanks!
Teken Posted August 24, 2017 Posted August 24, 2017 The unit is RF only so you need to ensure you have a solid dual band Insteon network. Since you have the outlet I am going to assume its the dual outlet which is RF and Powerline. If so ~ Good to go . . .

As long as the room temp does not exceed the spec'd operating range for the stat, it should be an ok solution .. 104F is the highest spec'd for it Its not dual band, its RF only, so it needs to be in solid range of another repeating dual band device. Yes, you can easily power it with a plug in 24VAC step down transformer. If you search for that model on the forums here you'll find people don't always get the degree per degree feedback into the ISY that they want, so programs for it could be If gearroom temp => x then set fans on else wait 5 minutes set fans off In my experience automated fans can kick the temp down quickly artificially. I run into this with my attic. I keep the fan going a while after the target temp is sensed. You can calibrate that time up and down to what you find in your room Paul
GQuack Posted August 25, 2017 Author Posted August 25, 2017 Thank you for the responses. Yes, the outletlinc is going to be 1-3 feet away from the thermostat, should be no problem with the RF signals. I'll look for the power step-down transformer and go from there.
stusviews Posted August 25, 2017 Posted August 25, 2017 HVAC transformers are plentiful. Because you won't be switching a compressor or furnace. even the least costly is adequate, so your only concern is installation (i.e., how it's mounted)..

GQuack Posted August 25, 2017 Author Posted August 25, 2017 You guys are all awesome, kind, timely, and helpful responses, thank you so much. Here's the one I ordered before I saw larryllix's response. Figured since they are a thermostat company they should know. http://www.store.radiothermostat.com/24VAC-Transformer-CT-Transformer.htm
Teken Posted August 25, 2017 Posted August 25, 2017 Ensure you verify communications is fine after you install the new transformer. The most critical is via the Admin Console where you can see real time status updates. Often times you will be able to see local status just fine. But that same status doesn't reflect what happen locally. Plan to have a Insteon Filter Linc at the ready should this problem arise. Sent from my iPhone using Tapatalk
GQuack Posted August 25, 2017 Author Posted August 25, 2017 Thank you Teken, I will take note of that. And..I do have a FilterLinc on hand should it be necessary.
