Temperature Control

A controlled climate zone uses setpoints to determine when the zone will be
heated or cooled. A zone may be configured to use only heating, cooling, or
a combination of both to maintain a temperature. Depending on the system
mode, a zone may use either one (single) or two (dual) setpoints to regulate
temperature.
•
Single Setpoint (available for Heat, Cool or Auto modes): When
using a single setpoint to regulate temperature, a single setpoint is
used for regulation at all times, regardless of whether the system is
heating or cooling.
NOTE: When using a single setpoint, the controlled zone has a
20-minute change limiter to prevent system toggling.
•
Dual Setpoints (for use in Auto mode only): When using dual
setpoints, separate heat and cool setpoints are used. When the
ambient temperature drops below the heat setpoint, the controlled
zone will call for heat to maintain the heat setpoint. When the
ambient temperature rises above the heat setpoint, the controlled
zone will not call for cooling until the temperature exceeds the cool
setpoint. When the ambient temperature drops below the cool
setpoint, the controlled zone will not call for heating until the
temperature is below the heat setpoint.
NOTE: When dual setpoints are used, the P-TSTATRF in the
controlled zone will display the setpoint closest to the ambient
temperature.
For instructions on setting the system mode, refer to "Set the System Mode"
below.
To set the temperature:
•
Single Setpoint:
Click k or j to raise or lower the temperature setting.
NOTE: When using a single setpoint, there is a 20-minute change
limiter to prevent system toggling.
•
Dual Setpoints:
1. Verify that the controlled zone is set to the Auto mode.
2. To lower the heating or cooling setpoint, click the j button
under the setting to be changed. To raise the heating or
cooling setpoint, click the k button under the setting to be
changed.

Set the System Mode
