Temperature Controller Installation

Indoor models have their controller built into the front panel. A kit is available that allows the integrated controller to be removed and used as a remote controller. Additional controllers can also be installed.

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 temperature controller could be splashed with liquids.

Do not install in locations where it can be adjusted by the public.

Configurations

A maximum of 4 temperature 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 temperature 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.

Cable Lengths and Size

The cable for the temperature controller should be a non-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.
