Temperature Control - Rheem Integrity 20 Owner's Manual And Installation Instructions

TEMPERATURE CONTROL

Rheem controllers enable the user to control the temperature of the delivered water
from the outlet of the water heater. There are three controllers suitable for installation
with this water heater. They are the Kitchen controller, Bathroom1 controller and
Bathroom2 controller. One, two or three controllers can be installed. A Bathroom2
controller can only be installed if a Bathroom1 controller is installed. Only one of
each type of controller can be connected to the water heater.
The temperature settings of each type of controller are:
Bathroom1 & 2
Kitchen
The installation of Bathroom controller/s only (ie. no Kitchen controller) limits the
outlet temperature of the water heater to a maximum of 50ºC, regardless of the
preset outlet temperature of the water heater. If Rheem controllers are not installed,
the water heater defaults to the preset outlet temperature. Other manufacturers'
controllers cannot be installed with this water heater.
