Are there any unusual steps I need to take, when installing the thermostats, due to the two zones? thanks!

Usually there are just two wires to connect although if the thermostat also controls air conditioning then there may be three wires. __________________ The disadvantages of crab apple trees.

If it is hot water than it is usually only 2 wires, if it also controls ac than you might have 4-5 This how it is usually with ac White and red =heat red is jumped from rh to rc. Most tstats the jumper is already installed yellow= ac green = fan relay
