FOR THE USER
IVT Greenline HT Plus E
Reset button
Press in the button if the overheat
protector on the electric cassette
has tripped. The button is located
on the side.
Heat carrier pump
The pump ensures the heating
water circulates within the heating
system.
Compressor
The compressor increases the
pressure of the refrigerant.
The temperature of the vapour
increases from 0ºC to approxima-
tely +100ºC. The compressor is
insulated to decrease the noise
level.
Socket
Connections for the mains supply
as well as sensors.
Control panel
The control panel has a back-
ground lit menu display with four
rows of text information, three
buttons and a dial.
Distribution box
The distribution box is enclosed.
It houses a reset function for the
motor cut-out as well as miniature
circuit-breakers (MCB) for the
heat pump and electric cassette.
Heat transfer fl uid pump
The pump is insulated and features
an anti-corrosive fi nish. It ensures
the heat transfer fl uid circulates
from, e.g. the rock into the heat
pump.
Control unit Rego 637
The control unit is enclosed. It
controls and monitors all heat
pump functions.
Expansion valve
Lowers the pressure of the refrige-
rant that is to enter the evaporator
and collect energy from, e.g. the
rock.
Sight glass
Sight glass to check the level in the
refrigerant circuit. Air bubbles must
not form in the sight glass when the
heat pump is running. However, there
might be bubbles when the heat
pump is started and stopped.
Flexible hoses
The hoses counteract
vibrations in the heat pump.
Evaporator
The evaporator evaporates the
refrigerant to gas and transfers
heat from the heat transfer fl uid to
the refrigerant circuit (behind the
heat pump).
Particle fi lter
The fi lter can be opened for easy
cleaning. It also has a shut off
function.
Electric cassette
The electric cassette is used
to provide extra output in cold
weather conditions, with large
water consumption and at hot
water peaks.
Three-way valve
The valve switches between
heating the heating water and hot
water.
Condenser
The condenser condenses the
vapour to fl uid again and transfers
the heat to the heating system.
