Go Wireless With PTAC Thermostats

PTAC units have been around for a very long time but unlike conventional air conditioners they have been controlled mostly by the on board panel which can either be knob control or digital touch pad control. PTAC manufacturers have always offered a wall thermostat accessory but unless you were installing your PTAC from scratch it was bit of a chore to retrofit them to existing units because you needed to run wires from the PTAC unit to the thermostat which meant running the wires behind walls. In older buildings this was a difficult process. Now that has all changed with new "wireless" thermostats that allow you to control your PTAC units instantly without the need to run wires. There are several models available today which allow you to simply control the unit from the wall thermostat to more advanced systems which give you the ability to control all your PTACs from a central location or smart phone. This has become very popular especially in hotels who need to be able to manage and control their guest room heating and cooling costs which is about 40% of their energy costs. The T631W-2 from PRO1 is the most affordable wireless PTAC thermostat on the market today. They range in price from $89 to $129 depending on the quantity you purchase. The T631W-2 will operate on both heat/cool and heat pump models across many major brands including Friedrich, Frigidaire, GE, Amana, LG as long as the PTAC unit has a built in interface terminal block which most late model units do.  It can either run on 2 AA batteries or you can hard wire it. The T631W-2 has a high and low fan speed control with a large 2 square inch blue back light display. It is non-programmable but you can preset your minimum and maximum temperature limits. The T631W-2 can operate up to 100 feet with no obstruction and up to 50 feet in standard residential construction. You can self install the T631W-2 in as little as 15-20 minutes.
