Fire Hazard
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
improperly, 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.
