## Questions & Answers

**Q: Is this a compatible replacement for Totaline P374-1800?**
A: Yes

**Q: I have a T-1700. It died after 9 years. Can it be repaired?**
A: I suspect it would cost more to repair it than to buy a new one.

**Q: If power shuts down, does the stat remember program settings?**
A: Yes it does, i have had a few power outages and have done service on AC and shut off power and still have not needed to reprogram it it just goes back to the settings it was on befor the outage. Hope this helps!

**Q: Does this require a c wire?**
A: I bought my Venstar to control my heating and A/c via Indigo Software. I replaced an existing A/C and Heating Digital Thermostat. There are several youtube videos to wire the Venstar T1800. I am assuming you are asking about the C wire which should be the "Common" or ground wire and I think that would really be needed. Here is some info from EHow about installing the Venstar. Connect the wires to the new thermostat. If the old thermostat's wire designations do not match the new thermostat, use this guide: G or F (Fan) connects to G; Y1, Y or C (Cooling) connects to Y1; W1, W or H (Heating) connects to W1, O or B; Rh, R, M, Vr or A (Power) connects to R; C (Common) connects to C; O/B (Rev. Valve) connects to W1, O or B; Y2 (2nd Stage Cool) connects to Y2; W2 (2nd Stage Heat) connects to W2.
