WIRING

The #950-1067 Timer/Relay may be used to replace either the 24 VAC input #950-1060 or the 115 VAC input #950-1065
Timer/Relays. The #950-1067 is designed to accept either 24 VAC or 115 VAC control input signals. The control inputs are non-polari­ty sensitive, meaning that the “hot” and the “neutral/return” can be connected to either side of the control input.

The output or motor switching side of the #950-1067 has three terminals. Viewing the Timer/Relay as depicted in diagram “1”, L1 or
the “hot” power lead is attached to terminal L1. L2 or the neutral/return lead is attached to terminal L2 and the Black or “hot” motor
lead is attached to terminal BLK. MOTOR. NOTE: In order for the timer to operate after appliance shutdown, terminals L1 and L2
must be powered continuously with 115 VAC.

The Timer/Relay kit is supplied with quick-connect leads for when it is installed as an accessory control. In most cases it will be easier
to use the existing wire leads when installing it as a replacement for a defective Timer/Relay.
