Upload from disk. See Figure 7 and Figure 8. The delay overrides any Load Demand and does not allow the N. See Figure 6. The delay may be set for 0 to 12 minutes in 1-minute increments. For example, if the anti-short cycle delay is set for 7 minutes, the A control will not restart the equipment for 7 minutes after the equipment has cut out, even if the cut-in temperature value is reached.
If the temperature reaches the cut-in value during the delay period, the display flashes between the sensed temperature and ASd , indicating that the next On-cycle is being delayed.
After the set delay time has elapsed, the A control returns to normal operation, restarts the equipment if cut-in has been reached , ASd stops flashing, and the LCD reverts to the normal operating display. Note: Any interruption in supply power to the A control activates the anti-short cycle delay.
Sensor Failure Operation SF establishes how the A control operates the equipment in the event of a sensor or sensor-wiring failure. The A control may be set to run the equipment continuously or to shut it down if the sensor or sensor wire fails. The control implements a 1-minute delay before initiating a failure response to allow for verification of the failure condition and to avoid nuisance failure indications.
The Temperature Offset function is used to reset the Heating Setpoint to a lower temperature secondary setpoint or reset the Cooling Setpoint to a higher temperature secondary setpoint by the temperature value set in Temperature Offset. See Wiring. This function enables the control to alternate between two temperature setpoints based on the position of the binary input switch. See Setting Other Functions. When the circuit is closed between the binary input BIN common COM terminals, the offset function is enabled and the A control cycles on the secondary setpoints.
Positioning the Jumpers in the Adjustments section. See Figure 12 and Figure Touchpad Lock: The jumper at P5 establishes whether the touchpad is locked or unlocked. Locking the touchpad deters accidental or unauthorized changes to all of the function parameters.
See Figure Setpoint Mode: Removing or installing the lower jumper at P4 establishes whether Setpoint is the cut-in temperature or cutout temperature. Position the jumpers located on the circuit board under the A control cover to set the desired mode of operation. See Positioning the Jumpers. The output relay energizes and the LED illuminates when the temperature rises to Setpoint. When the temperature drops to Setpoint minus the differential value, the relay and LED de-energize.
