Number of Stages
This refers to the number of heating or cooling sources that may be controlled by a
single thermostat. For example, if a system contains baseboard heat, a hot air system
and air conditioning, then there are two heating stages and one cooling stage. In this
example, a 2 heat/1 cool thermostat should be installed. Note: If you have auxiliary heat
(backup heat, such as a fan coil or baseboard), that counts as a second heating source.
The number of stages may be written in several different ways. The most common are
2H/1C or 2 Heat/2 Cool; both mean that there are two heat sources and one cool
source. The number of stages can vary from single heat or single cool up to 4 Heat/3
Cool on a single thermostat.
User Interface
Thermostats are operated using a digital touchscreen, buttons with a digital screen, or
simple mechanical dial. Our most popular touchscreen thermostat is the Honeywell
TH8110U1003.
Mount
Thermostats may be mounted horizontally or vertically depending on personal
preference and space constraints.
