Mode
Auto
In the Auto mode, the controller automatically switches between heating
and cooling the space. However, the heating operation has priority over the
cooling operation. In this mode, the minimum slab or floor temperature is
maintained even when the controller is cooling the air.
Heat
In the Heat mode, the Heat 1 relay operates to satisfy the heating
temperature requirement of the zone, and disable the cooling mode.
Cool
In the Cool mode, the Cool relay operates to satisfy the cooling temperature
requirement of the zone, and disable the heating mode. When using a slab
or floor sensor, the slab minimum temperature is ignored.
Off
In the Off mode, the Heat 1 and Cool relays do not operate.
Note:
If an air, slab or floor sensor is active in the Off mode, a freeze-
protection function enables, allowing the Heat 1 relay to operate
and keep the zone above 35°F (2°C).
Heating and Cooling Interlock
Time Interlock
The SetPoint 512 features a Cooling Interlock setting to prevent frequent
changes between heating and cooling. Once the Heat 1 relay is off for a
minimum of one heating cycle or the length of the Cooling Interlock,
whichever is longer, cooling is permitted.
Temperature Interlock
In the Auto mode, the cooling temperature is limited to 3°F (1.5°C) above
the heating temperature. If the cooling temperature is set below the heating
temperature, the controller automatically adjusts the cooling setpoint.
When operating in the Cool mode, there is no interlock between the
heating and cooling temperature.

ROOM TARGET
This displays the current desired air temperature
for the space (one active air sensor required). This
is only available when in the Installer access level.
(See
Figure 14
.)
ROOM
This displays the current air temperature for the
space that is the average of all active air sensors
(one active air sensor required). (See
Figure 15
.)
OUTDOOR
This displays the current temperature at the
outdoor sensor. (See
Figure 16
.)
Note:
SENS must be set to OUT.
SLAB
This displays the current slab or floor temperature
(one active air sensor required). If two slab or
floor sensors are present, this is the average
temperature. MIN is displayed when the slab or
floor minimum temperature is calling for heat.
The slab or floor sensor may call for heat even
though the room setpoint temperature is satisfied.
(See
Figure 17
