THE R841 ELECTRIC HEATING RELAY IS
USED WITH A 2-WIRE, 24V THERMOSTAT
TO PROVIDE CONTROL OF ELECTRIC
HEATING EQUIPMENT. IT IS A DIRECT-
FOLLOWING RELAY WHICH OPERATES
WITH EACH CYCLE OF THE THERMO-
STAT (4 TO 6 CYCLES PER HOUR).

❑ 

 models are used to control one

load.

❑ 

 is used either with one thermostat

to control two loads simultaneously, or with
two thermostats to control two independent
loads.

❑ 

 and E models include an integral

transformer; R841 D model must be powered
from a remote 24V transformer.

❑ 

 and D models have a 1/2 inch male

conduit bushing.

❑ 

The 

   and E models are for instal-

lation on a wireway or J-box.

❑ 

R841 E has a 1/2 inch male conduit bushing

and includes an enclosure with a low voltage
wiring compartment.

❑ 

Special 

 with 10 second minimum

timing between stages is available.

❑ 

Each relay switches up to a 5,000 watt load.

❑ 

Spst MICRO SWITCH snap switches are

actuated by ambient-compensated 
strips.

❑ 

Leadwires are provided for both line voltage

and low voltage connections.

❑ 

Small size and silent operation allow instal-

lation in living area, utility room, or basement,

❑ 

May be mounted in any convenient position.
