Essential Info

If you are using a Venstar 7-Day Programmable Digital Thermostat or 7-Day Dual-Fuel Programmable Digital Thermostat, the Venstar Add-A-Wireless Thermostat Kit will let you have remote control of that thermostat by using a Venstar Extra Wireless RF module and a Venstar T1100RF Wireless Thermostat, both are included. The RF module simply snaps into the RJ-11 phone jack on your existing thermostat and acts as a transmitter and a receiver. The T1100RF thermostat can then control the existing thermostat from up to 500 feet away. The T1100RF thermostat is battery powered so it can be used just like a remote control anywhere in your home. The thermostats can be linked in a matter of minutes. Managing the amount of time your HVAC system is running is a great way to conserve energy, and this kit gives you the ability to remotely turn it off any time from anywhere in your home. The T1100RF runs on 2 AA lithium batteries (included).

Note: This is not compatible with the Venstar 1-day programmable thermostat.

    works fine to adjust main thermostat from a separate bedroom, but not in programmable mode. Control keeps switching back to the main thermostat rather than the remote wireless unit. So I have to adjust manually from the remote unit every evening and morning. Venstar has been no help yet.

    Review for Venstar Add-A-Wireless Thermostat Kit Item# 30419 with the Venstar 7-Day Programmable Thermostat, Dual Fuel Item# 30412A I've been searching for a thermostat for my heat pump / central A/C that would do the following. 1) Lock out the emergency heat strips (2nd stage heat) durring smart recovery. 2) Lock out the heat pump when heat strips are running. 3) Programable 4) Runtime display for heat and A/C 5) Optional wireless remote sensors This unit dose all this and more, I'd bought two other thermostats from other Mfg. over the past year only to be disapointed. I ordered this with the optional Venstar Add-A-Wireless Thermostat kit and they work very well. Our FL off grade home has 10-12' ceilings, the wired thermstat was in a hall near a return, temp in living areas was always to hot or cold, with the remote thermostat we put it in the L.R. durring the day and MBR at night, now the temp is always right. Had it about 6 weeks, was a bit more expensive than I wanted to pay, but now that I have it our home is much more comfortable all the time,so far very pleased.

    This unit has truly saved us. We were struggling to keep our kids room warm enough without overheating the rest of the house. This unit is AWESOME. We put it in one of my son's room (the coldest room) and the heat cycles more often but for a shorter period of time than when controlled from the main thermostat location. The result is that my kids rooms are comfortably warm yet our room is actually cooler (and much more comfortable) since the heater has much shorter cylces. I expect to see significant savings in our heating bill as well! The only problem I had was that the wireless thermostat was that it was not calibrated correctly and gave falsely high readings. This was easy to adjust though with the manual provided with the unit. I LOVE THIS THING!!!!!

    Did not come with batteries as it says in the ad. Other than that problem thermostat works as expected.
