Outdoor Temperature Sensor Installation
Guidelines
•
Avoid installing the temperature sensor in a location where the
temperature may change due to direct sunlight or a location
where the representative outdoor temperature is not indicated.
•
The best place to install the temperature sensor is to the north
or northeast of the eaves, where direct sunlight can be avoided.
•
Do not install the sensor near a heat source that may affect
sensing of a correct temperature (fans, exhaust vents, lights).
•
Avoid installing the sensor in a location with a high amount of
moisture.
•
Use 18gauge wiring with no splices
•
Before attaching the cap, ensure the wiring is fixed firmly.
•
The sensor is a water resistant device.
Outdoor Reset Control
(Available with Optional
Outdoor Temperature Sensor)
The outdoor reset control can be used in order to improve the
energy efficiency. With the Outdoor Reset Control, the space
heating temperature setting automatically changes according to
the outdoor temperature and the current space heating system
application (system load)
Notice
The outdoor reset control can be used only when the outdoor
temperature sensor is installed. In addition, it only works when the
boiler is running in the normal operation mode. It does not work when
the boiler is running in either the Minimum(MIN) or Maximum(MAX)
mode, or When the boiler's front panel displays a fault.
The following tables list the default space heating temperature
range by system heat load and the applicable outdoor temperature
ranges.
