Remote Controller Installation

Location

•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 sounds.

The table to the right shows some of the possible combinations of controllers.
