The Dual-Level Temp relay may be mounted in any position
without affecting it's performance.
It can be connected using the 1/2" male conduit hub and can
be mounted to any standard junction box or wiring compartment.
It can also be mounted using the two holes in the back of
the case. Location of the mounting holes may be simplied by
holding the control against the mounting surface and marking
the proper position for drilling the holes.
INSTALLATION
All wiring should be done in accordance with local and national electrical codes and ordinances.
If a wiring diagram is supplied with the heating equipment, fol-
low those instructions. If none is available, two diagrams are
presented which show different wiring methods for the Silent
Operator relay.
OPERATION
As the thermostat closes its contacts, bimetal heaters #1 and
#2 are energized. Approximately 45 seconds later, the warping
action of these heaters closes line voltage switches #1 and #2
to energize heating loads #1 and #2.
When the thermostat opens its contacts, bimetal heaters #1
and #2 cool for approximately 45 seconds before line voltage
switches #1 and #2 open to de-energize the heating loads.
WIRING AND OPERATION
Use thermostat with a .4A xed
heater, or set adjustable heater
in thermostat at .4A.
