Flow Proof
To generate a flow proof, a voltage between 24 V (ac) and 240 V (ac) must be applied
across the Flow Proof terminals (5 and 6).
Output Connections --------------------------------------------------------------
Pump Contacts
The Pump 1 and Pump 2 terminals (7, 8 and 9, 10) are isolated outputs in the 132.
There is no power available on these terminals from the control. These terminals are
to be used as a switch to either make or break power to the pump circuit. Since these
are isolated contacts, they may switch a voltage between 24 V (ac) and 240 V (ac).
Alert Contacts
The Alert A and Alert B terminals (13, 14 and 15, 16) are isolated outputs in the 132.
There is no power available on these terminals from the control. These terminals are
to be used as a switch to either make or break power to the alert circuit. Since these
are isolated contacts, they may switch a voltage between 24 V (ac) and 240 V (ac).
Outdoor Sensor Connection ----------------------------------------------------
Do not apply power to these terminals as this will damage the control.
Outdoor Sensor (Optional)
Connect the two wires from the Outdoor Sensor 070 to the Outdoor Sensor terminals
(17 and 18). The outdoor sensor is used by the 132 to measure the outdoor air
temperature.
Note: If an outdoor sensor is not installed, the WWSD dial must be set to Off.
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 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 sensor.
Test The Sensor ------------------------------------------------
In order to test the sensor, the actual temperature at the 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 read-
ings compared. Test the sensor according to the instructions in the
Data Brochure D 070.
