Testing The Wiring - Kanmor 360e Data Brochure

Indoor Sensor
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 360e to measure the room air temperature.
Unoccupied Switch
If an external timer (kanmor Timer 032e) or switch is used, 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.
STEP FIVE
Each terminal block must be unplugged from its header on the control before power is applied for testing. To remove a termi-
nal 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 persons.
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.
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 instruc-
tions in the Data Brochure D 070e.
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
207 and 253 V (ac).
Test The Powered Inputs
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) at the terminals.
When the mixing demand device is off, you should measure
less than 5 V (ac).
