Testing The Wiring - Kanmor Zone Control 369e Manual

Table of Contents

Zone 3 (tN1 3)

Connect the Com terminal from the RTU to the Com terminal (24) on the 369e. Connect the tN1 terminal from the RTU

to the tN1 3 terminal (25) on the 369e.

Zone 4 (tN1 4 or Indr 4)

Connect the Com terminal from the RTU to the Com terminal (24) on the 369e. Connect the tN1 terminal from the RTU

to the tN1 4 terminal (26) on the 369e. If an indoor sensor is used, connect the two wires from the sensor to the Com and

Indr 4 terminals (24 and 27).

Note: If an RTU is connected to tN1 4, an indoor sensor can not be connected to Indr 4.

Zone 5 (tN1/2 5)

Connect the Com terminal from the RTU to the Com terminal (28) on the 369e. Connect the tN1 terminal from the RTU to

the tN1/2 5 terminal (29) on the 369e.

Zone 6 (tN1 6 or Indr 6)

Connect the Com terminal from the RTU to the Com terminal (28) on the 369e. Connect the tN1 terminal from the RTU

to the tN1 6 terminal (30) on the 369e. If an indoor sensor is used, connect the two wires from the sensor to the Com and

Indr 6 terminals (28 and 31).

Note: If an RTU is connected to tN1 6, an indoor sensor can not be connected to Indr 6.

Two Stage RTUs and Indoor Sensors

RTUs and indoor sensors provide indoor temperature feedback to the control. An indoor sensor can only be used for the

even numbered zones (i.e. zones 2, 4 and 6).

Note: The wires form the RTU are polarity sensitive. The RTU does not operate properly if the wires are reversed.

Zone 2 (tN1 2 or Indr 2)

Connect the Com terminal from the RTU to the Com terminal

(20) on the 369e. Connect the tN1 terminal from the RTU to

the tN1 2 terminal (22) on the 369e. If an indoor sensor is

used, connect the two wires from the sensor to the Com and

Indr 2 terminals (20 and 23).

Note: If an RTU is connected to tN1 2, an indoor sensor can

not be connected to Indr 2.

Zone 4 (tN1 4 or Indr 4)

Connect the Com terminal from the RTU to the Com terminal (24) on the 369e. Connect the tN1 terminal from the RTU

to the tN1 4 terminal (26) on the 369e. If an indoor sensor is used, connect the two wires from the sensor to the Com and

Indr 4 terminals (24 and 27).

Note: If an RTU is connected to tN1 4, an indoor sensor can not be connected to Indr 4.

Zone 6 (tN1 6 or Indr 6)

Connect the Com terminal from the RTU to the Com terminal (28) on the 369e. Connect the tN1 terminal from the RTU

to the tN1 6 terminal (30) on the 369e. If an indoor sensor is used, connect the two wires from the sensor to the Com and

Indr 6 terminals (28 and 31).

Note: If an RTU is connected to tN1 6, an indoor sensor can not be connected to Indr 6.

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 placed alongside the one to be tested and

the readings compared. Test the sensors according to the instruc-

tions in the Data Brochure D 070e.
