If you're posting a request for installation help, please provide as much info about your system as possible. For example, for help regarding connecting a smart thermostat, please include details about your system including whether you have gas/electric, heat pump, number of heat stages, A/C condenser, etc.

Programmable thermostat for 3 heat sources.

We are building a house next year and the location does not have gas available. We want to avoid LP or oil heating. So we are installing A pellet boiler, electric heat pump and electric heating elements as a back up.
Stage 1 Heat pump
Stage 2 Hydronic/Pellet boiler
Stage 3 Electric heat - Emergency heat

What I am looking for is a thermostat that will allow me to program each Heat stage individually or to program the delay between each stage. The main reason for this is to avoid using stage 3 as much as possible because electric is expensive.

If I cannot find thermostats that allow this to be programmed I will probable resort to using delay on make relays. Would just be easier to have thermostat that is very friendly to programming options.

    Ecobee allows you to configure temperature set points for each stage. I think you would have to configure as 2 stage heat pump with electric backup. Not sure how that would affect operation.
