CHAPTER 3: Configuring the Thermostat Using the TMI
Cool Control Specify the HVAC control of this thermostat. This parameter
describes the thermostat’s capability to control a single stage or
dual stage cooling system. The thermostat can also be disabled
from controlling a cooling system and instead operate as a
heat-only thermostat. (See Heat Control (page 3-37).)
Disable – Specifies that there is no cooling system present.
(heat-only thermostat.)
1C – Enables the cooling system as a standard single stage
system.
2C (default) – Enables the cooling system as a dual stage
system.
2
nd
Stage Offset
Specifies the second stage cool set point temperature referenced
to the first stage cool set point temperature. This parameter is
only enabled when 2H Cool Control is selected, otherwise it is
disabled. (e.g. If the first stage temperature set point is set to
72°F, and this parameter were set to 3°F, the second stage A/C
would activate at or above 75°F). Temperatures include:
0, +2, +3, +4, +5, +6
°
F (0, +1.0, +1.5, +2.0, +2.5, +3.0
°
C) –
Second stage A/C temperature offset from first stage A/C set
point temperature.
If Your HVAC System is a Heat Pump
Reverse Valve Polarity Enables you to control the direction of the heating and cooling
modes.
O – Indicates that the heat pump normally runs in heat mode
and when the reversing valve is activated then the heat pump
will run in cooling mode.
B – Indicates that the heat pump normally runs in cool mode
and when the reversing valve is activated then the heat pump
will run in heating mode.
Heat Control Specifies the HVAC control of this thermostat. This parameter
describes the thermostat’s capability to control a heat pump
system. The thermostat can also be disabled from controlling a
heating system and instead operate as a cool-only thermostat.
(See Cool Control (page 3-39).)
Disable – Specifies that there is no heating system present.
(A/C only thermostat.)
2H (default) – Enables the heat pump as a dual stage heating
system.
1H – Enables the heat pump as a standard single stage
heating system.
