Installation
Indoor Sensor (European version only)
If an indoor sensor is used, connect the two wires from the sensor to the Com and Indr terminals
(16 and 18). The indoor sensor is used by the Stk# 31360 to measure the room air temperature.

Unoccupied Switch
If an external timer or switch is used to provide an unoccupied period, connect the two wires from
the external switch to the UnO Sw and Com terminals (12 and 13). When these two terminals
are shorted together, the control registers an unoccupied signal.

Test The Sensors
In order to test the sensors, the actual temperature at each sensor location must be measured. A
good quality digital thermometer with a surface temperature probe is recommended for ease of
use and accuracy. Where a digital thermometer is not available, a spare sensor can be strapped
alongside the one to be tested, and the readings compared. Test the sensors according to the
instructions in the 10K Sensors L630070.

Test The Power Supply
Make sure exposed wires and bare terminals are not in contact with other wires or grounded
surfaces. Turn on the power and measure the voltage between the
Power L and Power N terminals
(3 and 4) using an AC voltmeter. The reading should be between 108 and 132 V (ac) for the North
American version and between 207 and 253 V (ac) for the European version.

Mixing Demand
Measure the voltage between the Mixing Demand terminals (1 and 2). When the mixing demand
device calls for heat, you should measure between 20 and 260 V (ac) for the North American
version. When the mixing demand device is off, you should measure less than 5 V(ac).

Step Five - Testing the Wiring
• Each terminal block must be unplugged from its header on the control before power is applied for testing. To remove a terminal
block, pull it straight down from the control.
• The following tests are to be performed using standard testing practices and procedures, and should only be carried out by properly
trained and experienced proffesionals.
• A good quality electrical test meter, capable of reading from at least 0 - 300 V (ac) and at least 0 - 2,000,000 Ohms, is essential to
properly test the wiring and sensors.
