Omnipolar safety switch
The installation should be preceded by an omnipolar safety switch according
to overvoltage category III, which ensures disconnection from all electric power
sources.

Communication between the
EcoZenith and CTC EcoAir/CTC
EcoPart
The communication cable used is an LiYCY (TP) which is 4-core shielded
cable, where the communication-bearing cores are of twisted pair type.
This should be installed between the terminal blocks in the EcoZenith: G51
(Brown), G52 (White), G53 (Green) and heat pump 1, from which the other heat
pumps can be connected in series.
15.5
Low voltage 230 V/400 V (High
voltage)
Supply
400 V 3N ~ 50 Hz and protective earth.
The size of the group fuse is given in Technical data in the section for the
property owner.
Connects to terminal blocks marked L1, L2, L3, N, PE.
Max thermostat
If the heat pump has been stored in an extremely cold place, the max
thermostat may have been triggered. It is reset by pressing in the button on
the thermostat behind the front panel.
Always check on installation that the max thermostat has not tripped.
