In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
PLEASE!! explain the purpose of a manual switch over for heating and cooling.Have been having trouble with these this week and my guru is on vacation. For the most part the switches are use with boilers and HWC and the fan runs contantly.
Also they are using a three way valve to modulated the water with a pump that runs continiously.
Need some help with troubleshooting these systems.
