| Q | | Will a GemTech control a two speed blower?
|
|
| A | | Yes, but only on LOW or HIGH. Connect the G1 wire to the thermostat G terminal for low speed. Connect both G1 and G2 for high speed. If you wish to have a switch for high fan, in most cases, you can use the ALTERNATE FAN CONNECT and remove the GAS/ELECT jumper.
Connect the G1 and the Y wire to the Y terminal. Connect the G2 wire to the G terminal. Now the FAN switch AUTO is LOW fan, and the FAN switch ON is HIGH fan.
You must remove the GAS/ELECTRIC jumper in the thermostat for the alternate fan connection!
