***Trail for 30 days before collecting payment*** Returned to home to install wireless temperature sensor to the upstairs thermostat. I connected the sensor and gave it 100% temperature control for the zone. Paul asked if we could put the sensor in his son’s bedroom. This room has a half dome window without shade. Once we placed the sensor in this space we allowed it to adjust on its own and it reached the existing set point of 73º. The thermostat displays the temperature read by the wireless sensor and we discussed the importance of changing the batteries to ensure the upstairs space stays comfortable. The wireless sensor reached the 73º set point and shut off the unit. This is an immediate sign that the system is functioning and cooling properly and that the residual heat affecting the wall mounted thermostat should no longer be an issue. We will still give Paul 30 day trail before charging the card on file.
