TROUBLESHOOTING

LCD display, display back-light and green status indica- tor LED turn off in Power Stealing mode:

This “off” condition is normal for the control in power stealing mode when wired with a defrost timer or other device that interrupts electrical power to the control.

No control settings will be lost during this time, however, the installer must ensure that applications requiring power steal- ing are suitable for the control to be off during these periods.

Please note: if the built-in alarm feature of the control is to be used on systems that may interrupt power to the control, the control must be wired with a neutral wire and set in non- power stealing mode. This will keep the control continuously powered unless there is an actual power interruption or loss. In this case, the control will be able to signal an alarm for system power loss.

Display indicates “CaL” on power up.

Control was not calibrated. Return control for replacement.

Unit does not turn on, (LCD does not display anything):

-Check that wiring is correct.

-Make sure power is turned on.

-Check that wiring is under terminal blocks correctly.

-Make sure both switches inside control are set to proper position.

-If in Power Steal mode,

-Make sure the load draws a minimum of 2.5 amp AC. If not, wire per the Non-Power Stealing diagram.

-Make sure nothing "breaks/opens the load line, such as a defrost timer or any other device, with the alarm feature enabled. This would cause a false alarm. If the alarm function is enabled, wire per the Non-Power Stealing diagram.

Temperature differential is wider than set:

-Temperature change of customer's unit is fast, and the Anti Short Cycle delay setting may be overriding the “call” to activate the heat or cool. Solution – lower Anti Short Cycle delay.

Installation and Power Up:

False alarm sounds, temperature has not yet reached set- point setting. CUSTOMER must disable alarm (AL = 0), until setpoint temperature is reached, then set alarm delay time.

Customer Changes Setpoint Temperature:

False alarm sounds. CUSTOMER must disable alarm (AL = 0), while unit is adjusting to new temperature. CUS- TOMER must then set the alarm delay time when tempera- ture is reached.

Bin/Set Back

False alarm sounds. CUSTOMER must set the delay time with sufficient delay time to assure the Set Back temperature is reached before the alarm delay time has expired.

Note: If the Set Back temperature cannot be reached within 99 minutes (the maximum Alarm delay time), change the Set Back value to a lower number of degrees. If a lower set back can not be used, you may not be able to use the alarm feature.

Alarm Sounds, Reason Unknown:

CUSTOMER should make sure the Alarm (AL) delay time is great enough to cover other conditions when the unit tem- perature may not be able to stay within 5 degrees.

-Loading or unloading of stock and the doors are open. (Add sufficient delay time to the alarm delay).

-Power is lost to the control if the line is broken/open by a defrost timer or other device. (Wire control per the Non Power Stealing line voltage schematic and connect/add a neutral line connection).
