Smart Temp Smart Sensors measure both humidity and
temperature and are used when economy cooling is required or
when you wish the occupants to be able to makes limited
adjustments to the Viking operation.
Two versions of Smart Sensors are available. The display version
of the Smart Sensor is fitted with a backlit LCD and buttons that
permit the set temperature to be adjusted within the Heating
and Cooling set limits as set within the Viking controller if
enabled. See setting heating & cooling limits on page 15 in the
installer menu “Change Temperature Control Limits”
.
When displayed, p
ressing the “After Hours” button will s
tart the after-hours run timer for the
period of time pre-set in the Viking installer menu. See after hours run timer on page 15.
If displayed, the On/OFF button permits you to turn the Viking OFF
manually, overriding any time clock schedules if set. Pressing the On/Off
button again will return the Viking to its previous state, (if the Viking is
set to manual control
the Viking will be “ON”, if
under time clock control
the Viking will run its schedule and be on or off based on that schedule)
Sensor without Display
(P/N RS-SS)
The standard “Smart Sensor” simply measures temperature and humidity
without permitting local set point adjustment or display etc. This type of sensor is essential for use
as an outside air sensor and can be used for an inside sensor if required.
NOTE - this sensor is NOT water resistant and therefore should be mounted in such a way that
protects the sensor from rain.
Smart Sensors have their own set of “TT” terminals where you are permi
tted to connect a standard
2 wire dry bulb sensor for remote temperature monitoring. This input overrides the internal Smart
Sensor dry bulb sensor only. Humidity is still measured at the Smart Sensor.
Manuals are provided with the Smart Sensors that provide detail on the
functions and settings of the Sensors.
Smart Sensor Wiring
Terminals 1 & 4 power the Smart Sensor (12v DC +/- 4v is normal) while terminals 2 & 3
communicate data between each sensor and the Viking.
The sensors must be wired in series only and no two sensors should have the same DIP switch
address on the sensor network. If multiple room sensors are fitted, the Viking will control to the
average temperature / humidity of all these sensors. Alternatively if set under the installer menu
o
ption “ Change Sensor Performance” menu
shown on page 15, you are able to select High Heating
& Low Cooling when using multiple Smart Sensors
(Version 2.9 Viking firmware required).
Note, when short of cabling you may power the Smart Sensor locally from a 12VDC power supply and simply
connect the Viking to the Smart Sensor using terminals 2 & 3.
