INSTALLATION – CONTROLLERS
CONTROLLERS
The Rheem 874 and 876 series can be installed with Rheem controllers to enable the user to control the
temperature of the delivered water from the outlet of the water heater.
There are two families of Rheem controllers suitable for installation with this water heater. These are the
standard controllers and the Deluxe controllers.
Standard Controllers
There are three types of standard controller. They are the Kitchen controller (Rheem AU - Part 299850,
NZ - Part A299850), Bathroom 1 controller (Rheem AU - Part 299851, NZ - Part A299851) and the Bathroom 2
controller (Rheem AU - Part 299852, NZ - Part A299852). These part numbers include the controller cable
supplied with the controller.
The standard controllers are suitable for use on all 874 and 876 series models.
The standard controllers are identified by a ‘K’ (Kitchen controller), ‘B1’ (Bathroom 1 controller) or ‘B2’
(Bathroom 2 controller) located on the front bottom left hand corner of the standard controller.
Deluxe Controllers
There are three types of Deluxe controller. They are the Kitchen Deluxe controller (Rheem AU - Part 299858,
NZ - Part A299861), Bathroom 1 Deluxe controller (Rheem AU - Part 299859, NZ - Part A299862) and the
Bathroom 2 Deluxe controller (Rheem AU - Part 299860, NZ - Part A299863). These part numbers include the
controller cable supplied with the controller.
The Deluxe controllers are suitable for use on all 874 and 876 series models.
The Deluxe controllers are identified by a ‘K’ (Kitchen Deluxe controller), ‘B1’ (Bathroom 1 Deluxe controller)
or ‘B2’ (Bathroom 2 Deluxe controller), located under the front panel, to the bottom left hand corner adjacent
to the BATH FILL VOLUME label.
The standard and Deluxe controllers are designed to be hard wired into the water heater using either the
Kitchen controller cable or the Bathroom controller cable.
Notes:
Where more than one controller is installed, the second or third controller must be of the same family.
A standard controller can only be installed with another standard controller(s) and a Deluxe controller can
only be installed with another Deluxe controller(s). A standard controller(s) and a Deluxe controller(s)
cannot be connected to the same water heater.
One, two or three controllers can be installed. Only one of each type of controller can be connected to the
water heater. Therefore, a maximum of three controllers only can be connected to each water heater.
A Bathroom 2 controller can only be installed if a Bathroom 1 controller is installed and a Bathroom 2
Deluxe controller can only be installed if a Bathroom 1 Deluxe controller is installed.
An additional Kitchen controller cable or Bathroom controller cable can be used if an extension of the
cable length is required.
It will be necessary to cut an opposite end off both cables to be installed in order to wire them together.
Alternatively, the cables may be extended using two-core flex with a minimum cross-sectional area of
0.5 mm

.
Other manufacturers’ controllers are not suitable to and cannot be installed with this water heater.
Warning: Temperature controllers must not be fitted to this water heater (874 series) if it is installed as an
in-series gas booster with a solar water heater system because water at a temperature much higher than the
controller setting can be delivered. If a solar water heater is installed to an existing water heater installation,
then all controllers must be disconnected and removed.
