Floating Action Zones

• If a floating action actuating motor is connected to the terminals

Com 1-2 —1

—2

(19, 20 and 21), make sure power to the motor

circuit is off and install a jumper between the terminals

Com 1-2 — 1

(19 and 20). When the circuit is powered up, the valve should

start to open. If it does not, check the wiring between the terminal and the actuating motor and refer to any installation or

troubleshooting information supplied with the motor. If the valve closes instead of opening, the wiring to the actuating motor must

be reversed. If the valve opens correctly, turn off the power to the circuit and remove the jumper. Install a jumper between the

terminals

Com 1-2 — 2

(19 and 21). When the circuit is powered up, the valve should start to close. If it does not, check the wiring

between the terminal and the actuating motor and refer to any installation or troubleshooting information supplied with the motor.

If the valve closes correctly, turn off the power to the circuit and remove the jumper.

• If a floating action actuating motor is connected to the terminals

Com 3-4 —3 — 4

(22, 23 and 24), follow a similar procedure

to that described above.

• If a floating action actuating motor is connected to the terminals

(25, 26 and 27), follow a similar procedure to

that described above.

If this DIP switch is set to

Zone 2 Ventilating

, the 367 can operate a ventilation system

through output relay

. If the DIP switches are set to

Zone 1 Cooling

and

Zone 2

Ventilating

, the 367 can operate a free cooling system through output relays

and

. If

the DIP switch is set to

Zone 2 Heating

the 367 operates output relay

as a heating zone.

Testing the Control Functions

STEP SEVEN

OPERATIONAL TEST OF CONTROL FUNCTIONS

The Zone Control 367 has a test routine which is used to test the main control functions. The 367 continually checks the sensors and

displays an error message whenever a fault is found. See page 15 for the list of error messages. When the

Test

button is pushed, the

Test

light is turned on. The

Heat Required,

and

Optimum Start / Stop

lights are turned off and the individual outputs and relays are tested

in the following test sequence.

Test Sequence



Each step in the test sequence lasts 10 seconds. At the end of each step, the device continues to operate

until it is turned off in a later step.

During the test routine, the test sequence can be paused by pressing the

Test

button. The test sequence

remains paused at that point for up to 5 minutes. If the

Test

button is not pressed again while the test

sequence is paused, the control exits the entire test routine. Once the test sequence is paused, the

Test

button can be pressed again to skip to the next step. This can also be used to rapidly skip through the test

sequence. To reach the desired step, repeatedly press and release the

Test

button until the appropriate

device and indicator light turn on.

Step 1 -

The

System Pump

relay is turned on.

Step 2 -

If the

Com 5-6

common block is used for a single One Stage zone, the control

turns on relay

for 10 seconds.

- If the

Com 5-6

common block is used for two One Stage zones, the control turns

on relay

for 10 seconds and then turns off relay

and turns on relay

for

10 seconds.

- If the

Com 5-6

common block is used for a Two Stage zone, the control turns

on relay

and then, after 10 seconds, turns on relay

- If the

Com 5-6

common block is used for a Floating zone, the control turns on

relay

for 10 seconds and then turns off relay

and turns on relay

for

10 seconds.

- If an RTU is not connected to

RTU 5

RTU 6

, the control skips this step.
