4. Initial Start-up
General
After you have installed the heater, bleed the water system and the fuel supply system carefully.
Conduct a trial of the heater to check all the water and fuel connections for leaks and to ensure that they are secure. If the
heater suffers a fault during operation, the fault must be located and remedied.
Description and Operation
After the heater is installed and the TECC Card is programmed to reflect Function F4 (Preferred Function), the end user will
enjoy seamless comfort control. The TECC Card will now request the DBW 2010 rather than reverse compressor cycling
when heat is requested.
Air Conditioning Operation:
Display function F1, F2 and F3 - In air conditioning mode, the 3-way valve is de-energized and remains in a spring-loaded
position. The cooled water flows through the air handler and cools the drawn in recirculated air. The water temperature at
the chiller outlet is 39 - 50°F (4 – 10 °C) depending on the sea water temperature.
Heating Mode:
Display function F4 and F5 - The 3-way valve switches to the spring loaded position if the automatic mode switches to the
heating function (F4) or if “Heating operation with external heating” (F5) is selected. This means the heater is integrated in
the water circuit and heats the water to max. 144°F (62 °C). The heat is given off by the air handler. A storage tank should
be installed ahead of the heater if the water volume in the circuit is too small less than 2 1/2gal. (10 liters).
Cool Down Mode:
To ensure adequate volumetric flow during heater cool down, the control program of the TECC card has been adapted to
cool down the heater for 5 minutes. The Cool Down is active from program version 413 onwards.
