NOTE: Motor-off delay on a 7505P will be disabled if the safety and operating limits as shown in Figures 5 and 9 interrupt power to the control terminal L1.

Connect thermostat leads (if applicable) to the TR and TW terminals on the control or jumper the TR and TW terminals on the control as directed by the appliance wiring diagram.

NOTE: If the thermostat short cycles or operates improp- erly, it may require an isolation relay for proper operation. The Beckett A/C Ready Kit (part no. 51950U) provides this function. Wiring instructions are included with the A/C Ready Kit.
