4M: Furnace & Air Conditioning
4M1: Air Conditioning Operation
The boat is equipped with an electric
Marine Air
air
conditioning and heating System including three compressors.
Its outlets are located throughout the boat controlled by
thermostats in the saloon and in the master and forward
staterooms.
Switches in the AC Breaker Panel allow operation of the
system. For operation, you must have either shorepower
connected or the generator running, with both the “A/C Pump”
and at least one “A/C (Zone)” circuit breakers turned on as
required.
Be careful if using a shore power connection not to overload it! The air conditioners'
"Mode" setting allows them to heat or cool the vessel, and the thermostats will cycle them on
as needed.
The air conditioning control panel has symbols. The red dot/white dot button turns the
area on or off. The button with the fan blades symbol regulates fan speed. The red and green
thermometers control the temperature. Your settings are shown in the readout, and the led’s
show the system’s status.
4M2: Furnace
Concept
The boat is equipped with a
Webasto
Diesel
circulating hot water heating System. The furnace
is in the lazarette to starboard, and heats hot water
circulated for heating throughout the boat. In
Diesel mode it burns the same fuel as the engine,
coming from one of the tanks, using about two
quarts/hour. Every day operation is controlled by
thermostats to regulate the temperature in (1) the
pilothouse; (20) the master stateroom; (3) the
guest stateroom; and (4) the saloon. Individual
blowers, each with its own “off-low-high” switch
then force the air into each area of the boat from
small heat exchangers.
Operation
To run the furnace: The Webasto main switch on the AC
Electric Panel must be on; the green light will be lit. Then, adjust
any thermostat to the desired level. The furnace’s built-in
computer will warm up the furnace, supply heat until the thermostat senses it is warm enough,
then the furnace will go through a “cool-down” cycle. You need not do anything but set the
thermostat with the switch “on”!
