34 I-Wave Installation Guide

Setting Freeze Temperature (optional)

Overview

Freeze temperature programming will not appear unless the optional Intermatic Freeze Sensor

(178PA28A) has been installed. This is the only freeze sensor that will work with the P1353ME

Controller.

Power must be disconnected when connecting the 178PA28A sensor.

If Intermatic Freeze Sensor (178PA28A) has been installed, use the following procedure to

program freeze temperature.

Procedure

Use the <PROGRAM> button to advance to the

Freeze Temp setting, as shown. The 1st Circuit and

32°F are the factory default settings.

Use the <ARROW> buttons to modify the desired

freeze temperature trip point. The programming range

is 32° through 44° F.

After you have set the desired trip temperature, push

and release the desired ON/OFF button to indicate

which circuits should come ON when the trip temperature is reached.

When programming is complete, , press the <ENTER> button to save and exit, or the

<PROGRAM> button to save and advance to the next programming feature.

The display will look like the example shown at the

right when the Freeze Control feature is activated. In

this example, the freeze sensor was connected, enabling

the Freeze Control feature. Circuits #1 and #3 were

programmed to come on during a Freeze condition.

AUX1 and AUX3 will blink, indicating that the control

has activated these two circuits due to a freeze condition.

NOTE: You can override the circuits during a freeze condition by pressing and releasing the

corresponding ON/OFF buttons. This will turn the devices OFF. The override will only last one

hour, so if the freeze condition still exists after one hour, Circuits #1 and #3 will come back on.

NOTE: Freeze protection stays enabled until the outside air temperature exceeds the

programmed freeze temperature for more than one minute.
