Remote Controller Installation
The controller should be out of reach of small
children.
Avoid locations where the controller may become
hot (near the oven or radiant heater).
Avoid locations in direct sunlight. The digital
display may be difficult to read in direct sunlight.
Avoid locations where the remote controller could
be splashed with liquids.
Do not install in locations where it can be adjusted
by the public.
Configurations
A maximum of 4 remote controllers, including wired
and wireless, can be installed for a water heater or
bank of water heaters. Controllers can only be wired
in parallel. Controllers cannot be wired in series.
The 4 remote controllers can consist of multiple MC-
91’s or MC-502RC’s but only 1 BC-100V and only 1
MC-100V.
Any one of the 5 types of controllers can be installed
by itself and still operate the water heater. All
functions will be available with the exception that the
clock function on the BC-100V will only be available if
an MC-100V is also connected.
If 4 MC-91’s are installed, simultaneously press the
Priority and On/Off buttons on the fourth controller
until a beep sound.

polarized two-core cable with a minimum gauge of 22
AWG. The maximum cable length from each
controller to the water heater depends on the total
number of wired controllers connected to the water
heater.
