Description
Select the HVAC control for this thermostat. This parameter
describes the thermostat capability to control a single stage or
dual stage heating system. The thermostat can also be disabled
from controlling a heating system and instead operate as a
cool-only thermostat.
Disable – No heating system exists. (A/C only thermostat.)
1H – Enables the heating system as a standard single stage
system.
2H (default) – Enables the heating system as a dual stage
system.
Specify the second stage heat set point temperature referenced to
the first stage heat set point temperature. This parameter is only
enabled when 2H Heat Control
disabled. (e.g. If the first stage temperature set point is set to
70°F, and this parameter were set to -3°F, the second stage heat
would activate at or below 67°F). Temperatures include:
0, -1, -2, -3, -4, -5, -6°F (0, -.25, -.5, -.75, -1, -1.25, -1.5, -1.75,
-2, -2.25, -2.5, -2.75, -3. -3.25, -3.5°C) – Second stage heat
temperature offset from first stage heat set point temperature.
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
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.
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, +1, +2, +3, +4, +5, +6°F (0, -.25, -.5, -.75, -1, -1.25, -1.5,
-1.75, -2, -2.25, -2.5, -2.75, -3. -3.25, -3.5°C) – Second stage
A/C temperature offset from first stage A/C set point
temperature.
