FLOW PROOF DELAY (30 second Delay / 10 second Delay) -------------------------------------------------------------------------- --------------------------------------------------------------------------
The 132 allows a time delay for detecting a flow proof signal once a pump contact is turned on. The amount of time is adjustable
from 10 to 30 seconds through a DIP switch. If a flow proof signal is not present within the selected time, the control turns off the
first pump contact and turns on the second pump contact. An alert contact is activated to indicate the failure.
FLOW PROOF TEST --------------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------------
The 132 has a flow proof test in order to determine if the flow proof device has failed. Once the pump contacts are turned off, a flow
proof signal should not be present. If a flow proof signal is still present after 4 minutes, the control activates an alert contact and
displays an error message. Refer to the Error Messages section at the back of this brochure.
ROTATION ---------------------------------------------------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------------------------
The 132 has a function which automatically changes the operating sequence of the pumps based on Equal Run Time Rotation.
Equal Run Time Rotation is based on pump running hours and allows for equal usage of both pumps. The 132 uses the Frequency
of Rotation dial to set the rotation of the pumps.
The control rotates the operating sequence of the pumps when the pumps are off. In a constant circulation system where the lead
pump runs continuously, the control waits for up to 12 hours to rotate the operating sequence of the pumps.
Note: The Equal Run Time Rotation function is reset by pressing the Clear Alert button.
EXERCISING ------------------------------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------------------
The 132 has a built-in pump exercising function. This function is only operational if the Exercising / Off DIP switch is set to
Exercising. If a pump has not been operated at least once every three days, the control turns on the output for 10 seconds. This
minimizes the possibility of a pump seizing during a long period of inactivity.
Note: The exercising function does not work if power to the control or pumps is off.
WARM WEATHER SHUT DOWN (WWSD) ---------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------
When the 132 is used as a stand alone control, the pumps can be operated based on outdoor air temperature. The WWSD feature
is only operational when an outdoor sensor is installed and the WWSD dial is not set to Off. When the outdoor air temperature rises
above the WWSD setting, the 132 turns on the WWSD light. When the control is in Warm Weather Shut Down, the demand LED’s
are displayed if there is a demand. However, the control does not operate the pumps to satisfy these demands. If the 132 receives
a pump demand from a reset control, the outdoor sensor should not be installed and the WWSD dial must be set to Off.
PUMP OPERATION ---------------------------------------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------------
The lead pump contact closes whenever there is a pump demand and the 132 is not in WWSD. If a flow proof is not present after the
flow proof delay has expired, the control turns off the lead pump contact and turns on the stand-by pump contact. An alert contact
is activated to indicate the failure. The stand-by pump contact also turns off if a flow proof is not obtained once the flow proof delay
has expired.
FLOW PROOF ----------------------------------------------------------------------------------------- -----------------------------------------------------------------------------------------
A flow proof signal is required at all times during pump operation. A flow proof is generated
by applying a voltage between 24 and 240 V (ac) across the Flow Proof terminals (5 and 6).
Once voltage is applied, the Flow Proof light is turned on. Once a pump contact is turned
on, a flow proof signal must be present before the flow proof delay has expired. A flow
proof can come from a flow switch, pressure differential switch, current sensing switch, or
power sensing switch.
