The BlueCool V-Series air-conditioning system is operated with the control
element that enables access to all functions for normal operation of the air condi-
tioning system.
3.1 Directly connected air handlers
The central digital chiller control element not only controls the general operati-
on of the chiller unit but can also directly control the air handlers located in the
saloon and/or in the cabin (where the main cabin temperature sensor is located).
This direct air handler control function is not available in all installations.
NOTE!
When an air handler is connected directly to the BlueCool V-Series
chiller it acts as the reference and governs whether the system is to
heat or cool in automatic mode.
The secondary air handlers can only be operated in the same operating mode
(heating or cooling) as the chiller unit as the unit can either only heat or cool at
any one time.
NOTE!
By using electrical heating elements in the secondary air handlers
individual cabins can be heated while the overall system operates in
cooling mode.
3.2 Operation
All fans connected directly to the chiller electrical box are started when the ope-
rating mode LED lights up. The fan control facility checks whether the cold water
circuit is at the required temperature. Example: In cooling mode at a set tempe-
rature of 21°C, the fan speed in automatic operation remains at level 1 until the
temperature in the cold water circuit is lower than 21°C. This prevents the fan
starting up too early if the temperature in the cold water circuit is unsuitable.
The digital chiller control element can completely shut down fan operation, e.g.
at night, while the other air handlers on the boat continue to operate. The fan
control is completely independent of compressor operation.
