Installation
Mount the unit directly on a wall or to a wall box. For the
most accurate results, units should be mounted on an
inside wall to a wall box, away from any supply air
exhausts and other sources of heat or cold. The
enclosure cover is held in place with locking tabs
located each side of the bottom of the enclosure. After
installation the cover can be locked on with the #1
Phillips head set screw at the bottom of the enclosure.
Wiring
All terminals are marked on the board as to their function.
They are as follows:
POWER/COMMON - LCD Power Connections
/-) - Setpoint Resistance Output
/-)/ - Temperature Sensor Output
/-) - Override Output
FAN(+/-) - Fan Switch Resistance Output
LED(+/-) - Override Status LED Power Input
Comm Jack - Communication Connections for Handset
OCC IN - Active Low, Digital Input for OCC indicator on LCD
If the unit is only equipped with a sensor, then the sensor is wired
with the pig tail connections. Do not use wire-nuts for the connection.
Place the provided clip near the bottom of the enclosure and place the
sensor head-down in the clip.
The HATSRC can be customized to work with any building automation system. Because of this there are
many possible connection configurations. The above represents the standard configuration. However, other
possible combinations include a shared common for all options and/or the override switch shorting tem-
perature sensor (switch in parallel with the sensor).
If the unit has the LCD option then the scale can be set to either ˚C or ˚F via the Scale jumper. If the unit is
also equipped with the backlight option it can be enabled/disabled via the Backlight jumper.
The LCD display can be calibrated by adjusting the LCD ADJ pot.
The HATSRC series is an attractive, low profile enclosure that
incorporates a high accuracy temperature sensor used to monitor
room temperatures. Additional options are available that include
setpoint adjustment, manual override, fan speed,
handset
communication port,
and LCD
