## Questions & Answers

**Q: How big are the numbers on the thermostat screen**
A: I would say the numbers for the current temperature display are about 1 inch in heighth or about the same as most digital alarm clock readouts

**Q: how do you turn off the programable part of the thermostat?**
A: You just hit the off button and it will stop the program or you can send it and hit hold and it will hold the temperature you set it at. So if you’re planning to go on vacation set it on hold.

**Q: My Old Thermostat has 6 Wires, I read that someone installed this with 4 wires, will I have two extra Wires???**
A: If your old one had 6 wires attached, this is not the thermostat for you. 6 wire are usually 2 heat 2 cool. The 5th wire is for common to power the thermostat from the furnace transformer and the 6th wire is for either 2nd stage heating or 2nd stage cooling, depending on the system. This thermostat will not control 2nd stage heating. That has to be done by the furnace control and requires a jumper wire from W1 to W2.

**Q: Does anyone know if this can be set to have it's back-light on continuously?**
A: No.  Can not be set to be on continuosly.  It can be configured to momentarly come on if light button is pressed or either any key is pressed.  Mine is working good.  I mainly bought it for the adjustable temerature swing which I have set at 3 degrees.
