CBI QAT-R-DM-M Installation And Programming Manual

QAT-R-DM – (M or H) ELECTRONIC TIME SWITCH
Installation and programming guidance

GENERAL

: The programmable time switch can be used to automatically control pool pumps,
lights, geysers. etc.
Important Notes:
1. The time switch has a backup power feature which requires 12 hours to fully charge.
(A fully charged time switch will retain its program and time for up to 24 hours, in the
case of a power failure).
2. Pushing any button during a power failure will reduce the backup power period.
3. CBI advises that the time switch be installed by a suitably qualified person.
ISOLATE POWER BEFORE INSTALLATION
●
Install the time switch on either mini rail or din rail with the clock screen up-right.

For loads larger than 21A resistive or 10A inductive, connect a suitable contactor to the time switch output.
Refer to Figure 3 for connections.
