Optional remote control functions:
•Remote On/Off start up: The terminals 26 and 27 of the Edenpac heat pump enable a remote start up by means of a
switch or any other device. The heat pump is supplied with a jumper between these terminals. If this function is used, the
jumper shall be removed. Otherwise it shall be kept.
•Priority to heating: A heating device, whatever it is, is designed to heat the water of the pool only when the water
circulates. Most of the time, a pool is filtered between 6 and 8 hours a day. But such a time can’t be sufficient sometimes to
maintain the water at the desired temperature, depending on the seasons. This is the reason why the Edenpac, like all
models of ZPCE’s range, is equipped with the “priority to heating” function that will manage the temperature of the pool,
taking itself the time to do it without caring of the scheduled time of operation of the filtration.
Terminals 4 and 5 shall be connected to the terminals of the filtration timer (see attached diagram). Every hour, the contact
between 4 and 5 is going to be closed, starting up the filtration for 5 minutes. If after 5 minutes, the temperature of the
water is over the required temperature, the filtration shuts off for one more hour. Otherwise, the filtration and the heat
pump are going to keep on operating until the desired temperature is reached. By this mean, the user is sure the water is
always ready for bath, at day or at night.
If this option is not used, the heat pump will operate only while the filtration runs.
• It is possible to connect a remote control module (1) (with display) . To do this use terminals: 39-40 (signals A-B) and 42-
43 for 12 Vac or Vdc supply of the interface A1 card.
Important:
To connect the remote On/Off(2) functions, and/or ″heating priority″(3) , use cables with a section of at least 1mm².
Packing glands and cable inlets are available for passage of these cables into the unit.
To connect the remote module(1) (max. distance = 50 m) use a shielded cable of 4x0.75 mm² minimum (connected
the braid shielded on terminal 41 on the heat pump and the remote control module).

5. REGULATOR OPERATION
5.1 Presentation
The EVK setting thermostat with digital display is supplied fitted in the appliance, electrically connected and pre-
set in the factory for swimming pool heating.
Setting principle: a control sensor placed at the water inlet side of the heat pump measures the temperature in the
pool and compares it to the target temperature. If the water temperature becomes or is lower than the target
temperature, the regulator unit authorises heating after a set time of 180 seconds, the Led blinks and then
remains on.

Heat pump operating conditions:
• The outside temperature must be higher than +5°C (automatic shut-off by anti-frost sensor SD2) and below
+38°C.
• A sufficient water flow must pass into the heat pump.
Note:The heat pump stops heating the pool when it starts a defrost cycle that can occur when surrounding air temperature is
between 5 and 12°C. The operation of the compressor is interrupted but the fan keeps running, according to the information
provided by the defrost sensor SD3 which is factory-set to -10 °C in the refrigeration circuit. As soon as this temperature
increases to 3 °C, the fan switches off and a 120 to 300 second time period starts (depending on the compressor stoppage time)
before the fan and compressor restart simultaneously.
¾Possible traces of humidity at the base of the unit are due to normal condensation of the water vapour in the
air or due to the defrost cycle in progress (phenomenon visible if the additional condensation evacuation kit is not
used).
6.1 Check
• that the hydraulic connections are correctly tightened.
• that there is no water leak.
• that the appliance is stable (with a level gauge and spirit level).
• that the cables are correctly connected to their terminals.
¾Incorrectly tightened cables may cause overheating of terminals.
• that the cables cannot be damaged by sharp metal sheets or elements.
• the earth connection.
• that no tools or other objects have been left inside the appliance.
6.2 Start up the heat pump
• Switch on the heat pump power supply protection device located inside the filter control cabinet.
• Start filtration.
• Set the by-pass and setting valves* as follows:
- Valve V1 slightly closed to increase the filter pressure from 150 to 200g (0.15 to 0.20 bar).
- Valve V2 fully open.
- Valve V3 fully open.
- Valve V4 fully open.
- Valve V5 half closed.
* see paragraph 4.2.
If the valves (V4 & V5) are not present, open Valve V2 and close Valve V3 half-way.
• Check that the swimming pool water hydraulic circuit has been vented.
• start the heat pump if it is standby mode (red dot) by pressing for 3 seconds, ON appears on the display
for a period of 5 s before displaying the water temperature.
• Set the target temperature ( then or then ) => if the pool should be heated: Led blinks
and then remains on after approx. 2 to 3 minutes max. and the heat pump starts.
Note: with an EdenPAC 7 single-phase unit, the compressors start up one after the other (the N°1 then N°2) in 36 seconds
intervals.
Flow rate adjustment, read the refrigerating pressure and the temperature probes:
1) Press for 3 seconds ÎÎread the value with key :
- if the value expressed in bars is red with a high digit : the flow rate adjustment is too high;
-if the value expressed in bars is green : the flow rate adjustment is correct;
-if the value expressed in bars is red with a low digit : the flow rate adjustment is too low;
-if the value is flashing red, wait for the timeout of 5 minutes to elapse (return to the pull-down menu by
pressing )
2) Press ; Î Î are displayed;
3) Press to display the desired probe value in °C (return to the pull-down menu by pressing )
4) Press or press for 3 seconds to return to the temperature display.
Reminder:If, when setting the by-pass and setting valves, the flow rate is less than 1.5 m3/h the heat pump will not function
(the flow switch remains open and the regulator displays the message AId alternating with the water temperature). Adjust the
setting valves : -V5- (if present) or -V3- and -V1-.
When the heat pump is running:
-If the flow rate switch switches on or off for a period longer than or equal to 3 s, a timer of 130 seconds* min.
is activated before the unit starts again.

15
* For information: this time period may increase during a defrost cycle or if the compressor stop time is less than 180 s.
-In case of a power failure, a timer of 125 seconds starts when the power supply is restored before the unit starts
again.
Observation:when the water attains the target temperature (Leds and off) the heat pump switches off
automatically.
Reminder: the 3-phase heat pump is equipped with a phase order control system (KA1) used to check that the
phase order is correct at start up (and during operation) and to signal a phase order fault (regulator indicates dCP
fault and the orange led KA1 inside the unit is off. The green led remains on as long as phases L2 and L3 are
present). In that event, switch off and isolate the unit and it is sufficient to invert two phase wires directly on the
main supply terminal.
ATTENTION! this operation must be carried out by a qualified and authorised professional
6.3 Checking
Check that the heat pump stops heating when:
• the target temperature on the digital display thermostat is decreased.
• filtration is switched off or valve V2 or V4 closed.

6.5 Winter storage
• Set control in “standby” by pressing for 3 seconds , is displayed for 5 s before a small red dot
appears.
•Close the valves V2 and V3 of the BY-PASS.
•Open valves V4 and V5 next to the unit (if present).
• Drain the water condenser (RISK OF FROST)by unscrewing the two pool water inlet and outlet unions on
the side of the heat pump.
• Lightly retighten the two unions to avoid any risk of foreign bodies entering the condenser.
• Do not hermetically seal the unit (risk of condensation). A special-purpose ventilated cover is available
(optional accessory provided by ZPCE).
Incorrect winter storage automatically cancels the GUARANTEE.
7. MAINTENANCE INSTRUCTIONS
Tasks to be carried out by a qualified and authorised person:
The following operations must be carried out at least once a year:
• Clean the evaporator at the back of the heat pump (with a soft brush and gentle water spray).
- Never use a high-pressure cleaner for this operation -
• Check the settings.
• Check safety devices.
• Check sealing of the cooling circuit on the EdenPAC 6 & 8.
• Check electrical connections and terminals (retighten the supply cable terminals).
• Check earth connections.
• Do not use solvents to clean the outside of your unit, PAC NET offers an optional specific cleaning kit.
