[E-00] Vacuum mode
When recovering/vacuuming of the indoor unit is needed, field setting [E-00] should be
activated. It will force the unit into thermo OFF and will open the expansion valve of the
indoor unit R-134a circuit so full vacuuming is possible.
By default [E-00] = 0, set to 1 to enable the vacuum mode.
[E-04] Pump only operation
When commissioning and installing the unit it is very important to get all air out of the water
circuit.
Through this field setting the pump can be operated without actual operation of the unit. By
doing so this will enhance the air removal from the circuit. The pump can operate at different
speed:
[E-04] = 0 normal operation of the unit (default)
[E-04] = 1 low pump speed operation (pump only, unit is not operating)
[E-04] = 2 high pump speed operation (pump only, unit is not operating)
