Superheat function
You may choose between two kinds of superheat, either:
• Adaptive superheat or
• Load-dened superheat
MOP
The MOP function limits the valve’s opening degree as long as the
evaporating pressure is higher than the set MOP value.
Override function
Via the analog input a displacement can be made of the
temperature reference or of the superheat reference. The signal
can either be a 0-20 mA signal or a 4-20 mA signal. The reference
can be displaced in positive or negative direction.
The signal can be used to override the valve's opening degree.
External start/stop of regulation
The controller can be started and stopped externally via a contact
function connected to input terminals 1 and 2. Regulation is
stopped when the connection is interrupted. The function must
be used when the compressor is stopped. The controller then
closes the solenoid valve so that the evaporator is not charged
with refrigerant.
Relays
The relay for the solenoid valve will operate when refrigeration is
required. The relay for the alarm function works in such a way that
the contact is cut in in alarm situations and when the controller is
de-energised.
