Thermostats
Two stages heating/cooling or one stage
heating/cooling thermostats are available in
either manual or automatic changeover.
Programmable Electronic
Night Setback Thermostat
Heating setback and cooling setup with 7-day,
5-1-1 programming capability. Available in
2 heating/cooling or 1 heating/cooling
versions with automatic changeover.
Economizer Controls
The standard equipment offering is a fixed dry
bulb changeover control. In addition to the
standard offering, there are two other field
installed control accessories.
Enthalpy Control
Replaces the dry bulb control with a solid
state dry bulb and wet bulb changeover
controller which has a fully adjustable set
point. Enthalpy control offers a higher level of
energy savings potential than the standard
dry bulb control due to the additional wet bulb
sensing capability.
Differential Enthalpy
Replaces the standard dry bulb control with
two enthalpy sensors that compare total heat
content of the indoor air and outdoor air to
determine the most efficient entering air
source. This control option offers the highest
level of energy efficiency available.
