Configuring Heat Control
The
Heat Configuration
subsection permits the configuration of the heat control settings. The heat pri-
ority can be set as well as several maximum limits related to heat control.

Parameter Description
Heat Priority
The order in which heating equipment connected to the controller is turned ON. Three
options are available:
Duct Heater
– Duct heating is activated first, then perimeter heating (depending on the
heating demand).
Perimeter Heat
– Perimeter heating is activated first, then duct heating (depending on the
heating demand).
Simultaneous
- Duct and perimeter heating are activated simultaneously.
Maximum Discharge Air Setpoint
The maximum discharge air temperature setpoint. In heating mode, the duct heater is
limited when the discharge air temperature reaches this maximum setpoint. If the dual
maximum option is enabled, the actual airflow setpoint is reset between 13°C (55°F) and
the maximum discharge air setpoint by the heating load.
Maximum Outside Air Temp for
Perimeter Heat Control
Perimeter heating is disabled when the outdoor temperature exceeds this parameter.
Similar to the “maximum outside temp for duct heater control,” the “maximum outside
temp for perimeter heat control” helps reduce energy costs by limiting heat consumption
when it is relatively warm outside.
Maximum Outside Air Temp for
Duct Heater Control
Duct heating is disabled when the outdoor temperature exceeds this parameter. This
parameter ensures that the HVAC system is not heating the building more than
necessary when the outdoor temperature exceeds certain temperatures limits. In general,
this feature reduces energy costs by ensuring that the heating is not enabled when it is
relatively warm outside.
Air Flow Tab (VAV Balancing)
The
Air Flow
tab allows a user to configure a damper box, calibrate a VAV box, and configure flow set-
points. A brief description of each type of configuration parameter is outlined below.
