Reduced my energy costs!

Written By Doug, Orange, ca on Friday, April 23, 2010

I purchased the INSTEON thermostat so that I could shut it down as I was leaving
for work. I replaced my front door light switch with a KeypadLinc and programmed
one of the buttons to basically shut down my thermostat. I also added lamp
modules to turn off a couple lamps in my bedroom (LampLincs) and replaced other
switches throughout the house (SwitchLinc) so that when i leave for work,
nothing is left running. I saved about $150 in energy costs the first month.

Note: in order to "talk" to this thermostat from a KeypadLinc you need an Access

Oh, and I added a SmartLinc to the mix so that I can control this thermostat and
my lights from my iPhone. Very cool stuff.

Product Research


Overview: The 2491T7 package includes the Venstar T1800 programmable digital thermostat and an INSTEON 2441V RF adapter, allowing remote adjustment of the thermostat by your INSTEON home automation system.

Remote Control: The INSTEON remote control adapter allows you to recall stored temperature and mode settings from any INSTEON controller. You can program any button on an INSTEON controller to any temperature and mode on the thermostat. When turning off your lights for the night from your bedside KeypadLinc, you can also recall an energy-savings mode, minimizing the activity of your HVAC system while you're sleeping.

Note: The INSTEON Thermostat is an RF-only product; at least one Access Point is required to communicate with your plug-in or wired INSTEON-compatible devices (using two Access Points is recommended). The thermostat is not X10 compatible.

Installation: The thermostat requires power to function; if you do not have a common wire running to your thermostat from your heating/cooling equipment, you will need to run a new wire or install a thermostat Add-A-Wire Accessory kit.
