2.8 REMOTE CONTROLLER
A standard remote controller (MC-601) is supplied as a standard together with any outdoor model water heater. The
indoor models are supplied with a non-removable controller on the front panel.
However, it is possible to add up to three additional remote controllers on both product ranges (outdoor and indoor), to
be able to adjust the temperature of the hot water from different areas.
For professional and commercial applications we recommend installation in area reserved for specialized personnel.
When more remote controllers are connected to the unit, only one of them can be set as the main or the ‘Master’. The
additional controllers connected are recognized as ‘Sub’ controllers (secondary); they are generally intended for the
use in environments other than the kitchen: bathroom, laundry, etc. The maximum temperature they are allowed to
select is electronically limited to 50°C: this is to reduce the risk of hot water burns as much as possible.
Instructions for the installation of the remote controller are given below.
2.8.1 GENERAL INFORMATIONS
It is possible to connect to a water heater a maximum number of four controllers. The maximum temperature
that can be selected on the remote controller is the one set on the PCB. The remote controller is set to not allow
temperature selection over 50 ° C. To allow setting higher temperatures follow the procedure on the following pages.
Location
NOTE
•
DO NOT
install water controllers near a heat source, such as a cook top, stove or oven. Heat,
steam, smoke and hot oil may cause damage.
•
DO NOT
install water controllers outdoors unless protection from water/dust ingress and
sunlight are provided.
•
The water controller set as the
MASTER
water controller
MUST NOT
be installed in a
bathroom.
•
DO NOT
install water controllers in direct sunlight.
•
DO NOT
install water controllers against a metal wall unless the wall is earthed.
•
Water controllers
MUST NOT
be installed where chemicals such as benzene, alcohol,
turpentine, hydrogen sulphide, ammonia, chlorine or other similar chemicals are in use.
•
The Water controller is a water resistant device, however excessive exposure to water may
result in damage to the water controller. Durability is improved when positioned outside the
shower recess.
•
AVOID
direct exposure to water or steam as these conditions may cause a malfunction.
•
Water controllers must be installed in shaded and clean locations.
•
They should be fitted out of reach of children (suggested height from floor to be at least 1.5m).
Water controllers
MUST BE
installed at least 40cm above the highest part of a sink, basin or
bath.
•
When cleaning your water controller use
ONLY
a damp cloth and a mild detergent.
Communication cable
Wired remote controllers operate at an extra low voltage (12 Volts DC) which is supplied from the water heater. A 10m
long communication cable is supplied for connection to the water heater. It is possible to prolong the communication
cable by using a similar one, up to a total max length of 50m. When connecting the cables to remote controller the
polarity is not important: either colour wire can be connected to either terminal.
It is not recommended to install the communication cable near by house electric cables: interference may easily
happen causing system malfunctions. In these cases we recommend to use proper shielded cables.
The installation of the connection cable is simplified by the presence of unique special connectors both on the electronic
board side and on the remote control side.
