Digital Display
The WEBASTO Digital Display gives access to information and controls at three distinct levels:
Immediate Access - Level 1
1. Room temperature readout in the main 4 LED display window
2. 3 small LED’s to the left indicating the operating cycle presently active: cool cycle only operation;
automatic cycle (switching governed by the end user’s entered setpoint temperature); heat cycle
only operation.
3. 2 setpoint keys give immediate access to the thermostatic setpoints for blower control (
and
keys). These keys are also used to alter programming values.
Secondary commands and info -Level 2
The
key gives immediate access to a number of secondary commands which need to be accessed
frequently for day to day operation. First access is to the blower speed control, then evaporator
temperature readout, etc.
Programming Commands - Level 3
A number of programming commands that do not need to be accessed for day-to-day operation are
hidden and require a special procedure to enable access and modification (See 5.1: "Programming
Access"). An access code can be enforced to avoid accidental modification of programming values.
Startup delay
After pushing the
key the LED’s will display
operation; the display will briefly show
cool, etc.) will come on after approx.15 seconds and compressor operation will start after approx.
50 seconds. The seawater circulation pump will come on approx. 9 seconds before compressor
startup.
Modification of setpoint temperature
The setpoint temperature, i.e. the temperature desired by the operator for blower operation can be
modified as following:
1. Press and hold one of the setpoint selector keys (
or
) and wait until the new desired
setpoint temperature is obtained.
2. Press
key to memorize.
The display will return to normal room temperature readout after approx. 5 seconds. Non-volatile
memory keeps last settings.
Special Features
Dedicated Blower speed key
The digital display provides for a dedicated blower speed key
which allows you to cycle through
the speed settings. The
key is only used for programming and setting purposes.
Self-priming pumps
WEBASTO Marine has developed a variable flow ultra-silent self-priming pump system. This will
automatically adjust its flow rate to the real required capacity, i.e. during a hot sunny afternoon the
pump will run at full speed, during the night it will slow down to minimum speed. This system is
referenced: WEBASTO WB200; it is basically a DC pump with a special control unit between the TCC
controller card and the pump allowing to adjust the pump speed as needed. The use of standard
115V/230VAC pumps is still possible without any restriction. Installation of WB200 pumps can be
above the waterline to 250 mm approx.
Flow rate varies between 6 and 12 L/min. approx.
