General Information
The wireless controllers are classified as short range radio communications devices
and referred to as ‘Low Interference Potential Devices’ (LIPD’s). They operate in the
same radio frequency as garage door openers and keyless automobile entry systems.
although interference with other LIPD’s is unlikely, it is not guaranteed interference will
not occur.
They should not be used if there is a chance of interference with other devices such as medical
devices and fire alarms. Please verify this before installation.
While the hot water outlets are open the set temperature may be lowered but not raised above
43 °C. also transfer of priority between controllers is not possible. These are safety features.
Radio communications
Safety features
Water controllers and transceivers do not contain serviceable parts and must only be
serviced and repaired by an authorised Rinnai Service Centre.
Servicing
Principle of operation
a wireless controller installation utilises a transceiver and up to 4 wireless controllers. There
is a ‘two way’ communication between the transceiver and controllers. The transceiver is
connected by electrical cable to the water heater. The transceiver transmits control signals
received from the wireless controllers operated by the user to the water heater. The transceiver
transmits operational status signals from the water heater to the controllers.
Water controllers allow precise temperature control by the user. When used correctly, the hot
water unit will deliver the selected temperature, even when the water flow is varied, or more
than 1 tap is in use. Each remote controller can be individually programmed, however the
water heater can only deliver 1 set temperature at any time.
Water resistance
The MC-503RC Wireless Water Controller is a water resistant device, however excessive
exposure to water may result in damage to the controller.
Do not immerse the controller in water
avoid direct exposure to water or steam as these conditions may cause a malfunction
always avoid exposure to water when the battery compartment is open
When cleaning your controller use only a damp cloth and mild detergent.
