11. Water filter
The water filter removes dirt from the water to prevent damage
to the pump or blockage of the evaporator. The water filter must
be cleaned on a regular base. See "9.5. Service and
maintenance" on page 25.
12. Pressure gauge
The pressure gauge allows readout of the water pressure in the
water circuit.
13. Flow switch
The flow switch checks the flow in the water circuit and protects
the heat exchanger against freezing and the pump against
damage.
14. Pump
The pump circulates the water in the water circuit.
15. Pressure relief valve
The pressure relief valve prevents excessive water pressure in
the water circuit by opening at 3 bar and discharging some
water.
16. Entry for power supply (PS)
17. Entry for high voltage wiring (HV)
18. Entry for low voltage wiring (LV)
19. Check valve
20. Safety valve
21. Electronic expansion valve
A Water side
B Refrigerant side
C Only for P-models
D Refrigerant flow in cooling mode
E Refrigerant flow in heating mode
Switch box of the hydraulic compartment (panel 1)
The switch box is factory pre-wired.
1. Main PCB (master)
The master main PCB (Printed Circuit Board) controls the
functioning of the unit.
2. Main PCB (slave)
(Only for EWAQ040~064* and EWYQ040~064* units.)
3. Control PCB
4. Input PCB (EKRP1AHTA) (optional)
5. Input PCB (EKRP1AHTA) (optional)
(Only for EWAQ040~064* and EWYQ040~064* units.)
6. Terminal block X1M
7. Terminal block X2M
Field wiring terminal block for high voltage connection.
8. Terminal block X3M
Field wiring terminal block for low voltage connection.
9. Terminal block X4M
10. Main switch
Allows connection of field wiring for power supply.
11. Pump relay K1P
(Only for EWAQ*BAW(P/H)* and EWYQ*BAW(P/H)* units.)
12. Overcurrent relay for pump K1S
The overcurrent relay protects the pump motor in case of
overload, phase failure or too low voltage. The relay is factory
set and may not be adjusted. When activated, the overcurrent
relay has to be reset in the switch box and the controller needs
to be reset manually.
(Only for EWAQ*BAW(P/H)* and EWYQ*BAW(P/H)* units.)
13. Cable tie mountings
The cable tie mountings allow to fix the field wiring with cable
ties to the switch box to ensure strain relief.

NOTICE
The electrical wiring diagram can be found on the inside of
the switch box cover.
Factory mounted options Descriptions
Hydraulic package (N) N (standard) contains flow switch,
filter, shut-off valves, pressure ports,
drain/fill valve.
Hydraulic package (P) Identical to N plus pump, expansion
vessel, safety valve, pressure
gauge.
High static pump (H) Identical to P but allows operation in
applications with high pressure
drops inside the hydraulic system.
Water piping heater tape (—H—) The water piping heater tape warms
up to prevent freezing of water inside
the unit during winter while the unit is
at stand still.
Low temperature cooling (B— —) Allows to cool glycol solution
(ethylene/propylene glycol + water)
down to –10°C.

High static pump
Optional kits Descriptions
Remote controller (EKRUAHTB) A second remote controller to control
the unit from 2 locations.
Input PCB (EKRP1AHTA) In order to remotely
• switch the unit on/off,
• select cooling/heating,
• select thermo on/off.
Electronic gauge kit (BHGP26A1) To monitor pressures in the
refrigerant system.
External control adaptor
(DTA104A62)
To execute demand control and low
noise control by external signals.
