2.3 HCE Technical Data
The control system has been tested and validated by the manufacturer for the following components:
Temperature sensors T1 to T5
NTC sensors 10 K (-30°C to 95°C)
Flow sensor, digital
Make EGE, LN 520 GSP 24 VDC / 70 mA
(Fz1 / Fz4)
Flow sensor, analogue
Make EGE, LN 520 GA 24 VDC / 4 ... 20 mA
(Fz2 / Fz3 sensors have to be calibrated by pairs for constant flow control)
Bypass
motor Bosch, Type VMC, 24V with potentiometer
(Type No. 0132801141 )
plug 192 840 3095 / socket contact AMP 962885-1
3. Power pack
The power pack (PP) is designed as a switched-mode power supply with active power factor correction. It is short-
circuit-proof with open-circuit and overtemperature protection.
In the standby mode, all 48 V and 24 V loads are switched off.
Input voltage:
230 VAC, 50 Hz
For fixed installation in building system, refer to electrical connection instructions.
Fuses:
single-phase mains 1x16 A external
three-phase mains 3x16 A external
internal mains fuse 2A M, internal on PP
internal fuse for GHX valve or frost prot. brine pump relay 0.1 A F on PP
Output voltages:
48 VDC, 200 W
24 VDC, 24 W
12 VDC, 24 W
Thermal protection:
1. All loads are switched off by HCE when the 1
st
threshold (approx. 65°C) is
exceeded
Æ
automatic restart when the control unit has cooled down.
2. 24/48V DC voltages from power pack are switched off when the 2
nd
threshold
(80°C) is exceeded
Æ
restart not possible until disconnection from power mains.
Standby:
System switched off via the programmer.
Rest period with reduced power input (approx. 2W) for entire system as all 24V and
48V loads are switched off; standby mode can be selected at the programmer
Switching function:
Connection of 230 VAC / 0.1 A control phase for the regulating valve of the ground
to air heat exchanger type Belimo, LM 230, or for relays controlling the frost
protection brine pump
External connections:
Single or three-phase supply (max. 5 x 2.5 connection line)
Voltage distribution for each phase 2 connections (L, N, PE)
1 x 48 VDC 200 W
PWM1 and PWM2 for supply & extract fans
Terminals for ground to air HX valve or for frost protection brine pump control relay
