I currently have the wired wall thermostat (2441TH) and I'm looking to add more control and monitoring for each level in my home. I have 3 of the remote control portable thermostats in my shopping cart right now (2441ZTH) - will this device solve the following goals:

1. Attic fan - I currently have an attic fan with an in-line box that requires manual settings for temp and humidity to trigger the unit to come on. If I cut the lines and run the insteon thermostat in there, will I be able to adjust the settings for temp and humidity that cause the attic fan to start?

1b. If 1a is true, will this setup also allow me to "override" the temp and humidity settings and manually turn the attic fan on whenever I want?

2a & 2b.Basement Dehumidifier. The questions are basically identical to the attic questions. The dehumidifier units I'm looking at have humidity triggers built in to the units - will connecting an Insteon thermostat allow me to adjust the humidity settings to trigger the dehumidifier to come on? and also allow a manual on or off whenever I want?

3. My currently installed Insteon wired wall thermostat is on the main level of my home. The second floor can be as high as 6-7 degrees warmer than the first floor. If I install this wifi unit (2441ZTH), and sync it to the wired wall unit (how?), will I be able to choose which thermostat settings are actually controlling the HVAC unit?

Many thanks for your assistance. I apologize if this has been answered before or if there is a FAQ or something. Please point me to where I can find the answers. Thanks again!

A maximum of two wireless thermostats can be used with the Insteon wired thermostat.

1 & 2. Are the fan and dehumidifier low voltage (24VAC) or line voltage (120VAC)?

They are line Voltage (120VAC).

Regarding the 2 wireless thermostats working with wired thermostat - my intention is to use the basement thermostat to control the dehumidifier manually and based on settings programmed into the thermostat itself and same for the attic one - they do not need to talk to the wired thermostat. Can these thermostats work independently of the main wired thermostat?

My intention is to only control the household HVAC system through the wired thermostat already installed and the wireless thermostat i plan to install on the second floor.

There's no limit to the number of independent wireless thermostats you can use.

You'll need an Insteon device such as an On/Off SwitchLinc, Micro Module or In-lineLinc to control the fan and humidifier. You'll also need software or an ISY to control the humidifier based on humidity.
