I have a Climatemaster TT30 049 with a groundwater loop field, and 2 hot water tank setup (one of the tanks is off, and connected to the desuperheater/HWG). How Climatemaster has this set up is that power to the HWG pump is connected through 2 temperature switches - 1 at the HWG (normally closed) and 1 at the compressor (normally open).

How this is supposed to work is that the switch at the HWG will allow the pump to run until it reaches a temperature threshold, I think like 125 or 135 deg. In case the DHW happens to be really hot, it will shut the HWG off.

Also, the switch at the compressor won't turn on until it reaches some temperature threshold, I'm not sure what this threshold is, maybe 115 or 125 deg, something like that. These are all factory supplied switches, but I am unaware if they give more information about these thresholds, only how to install them.

The problem is that my compressor (despite being on all day long) never engages this 2nd switch. The compressor is at something like 109 deg and never gets hot enough. So after months of waiting for the HWG pump to kick on, I decided to remove/bypass this compressor switch. Now, as long as the compressor is on, and the DHW is below maximum, the desuperheater/HWG will run.

Are there any downsides to operating this way? According to the installer, he felt that the compressor normally reaches "switch temperature" after only a minute of runtime, so this is "essentially" the same. Or, are there other switch options, so that I can choose the compressor temperature I would like to kick the pump on at, i.e. 105 deg?

Thank you.
