QAT -TRDM – ELECTRONIC TIME SWITCH
Installation and Programming Guide
General
The programmable time switch can be used to automatically control
pool pumps, lights, geysers, etc.
Important Notes
1. During a power failure, the
switch enters standby.
2. The time switch has a backup power feature which requires
30 minutes to charge.
3. In the event of a power failure, a fully charged time switch will keep time for up to 24 hours.
The programmed schedule is always retained.
4. CBI advises that the time switch be installed by a suitably qualified person.
Installation
1. Isolate supply power before installing time switch.
2. Install the time switch on either mini rail or DIN rail (remove the escutcheon clip for DIN).
3. Connect the time switch according to Figure 1 or Figure 2.
Use a suitable contactor (Figure 3) if necessary to switch higher current.
Observe markings for Line and Neutral poles.
4. Apply power and set the time and desired program schedule (see overleaf).
