SECTION II: INSTALLATION AND MAINTENANCE
Electrical connection of a motor-driven
pump/secondary circulation pump (VERSION PU-
PU/DP)
DANGER!
Electrical connection must be carried out by
qualified personnel in compliance with the
regulations in effect in the country where the unit is
installed. RHOSS shall not be held liable for
damage to persons or things caused by incorrect
electrical connection.
IMPORTANT!
Refer to the wiring diagrams enclosed with the unit
which highlight the terminals to be set up by the
installer.
If one of the pumps stops running, act on the
backup pump selector on the control board to
enable the backup pump.
II.2.5 REMOTE MANAGEMENT USING
CONNECTIONS SET UP BY THE INSTALLER
DANGER!
Electrical connection must be carried out by
qualified personnel in compliance with the
regulations in effect in the country where the unit is
installed. RHOSS shall not be held liable for
damage to persons or things caused by incorrect
electrical connection.
IMPORTANT!
Refer to the wiring diagrams enclosed with the unit
which highlight the terminals to be set up by the
installer.
SCR - Remote control selector.
SEI – Remote summer-winter selector (THAE-THAES only)
LF – Compressor function lamp.
LB – General malfunction lamp.
• Remote ON/OFF enablement (SCR)
Remove the jumper between the terminals (35 and 36 on models
TCAE-TCAES-THAE-THAES 470÷4160, 21 and 22 on models TCAE-
TCAES-THAE-THAES 230÷260) on the user interface terminal board
and connect the remote control ON/OFF selector cables.
CAUTION
Open contact: the unit is OFF.
Closed contact: the unit is ON.
IMPORTANT!
When the unit is switched OFF using the remote
control, E00 is displayed.
II.2.6 NOISE REDUCTION
IMPORTANT!
The unit is designed for outdoor installation;
therefore local and national standards in force
regulating noise levels must be complied with.
Incorrect positioning or installation may cause an
amplification of the noise or vibrations produced
while the unit is running.
○ During installation it is IMPORTANT to bear in mind the following:
• non-soundproofed reflecting walls near the unit (such as balcony
walls or the perimeter walls of a building), may increase the total sound
pressure level reading near the appliance by as much as 3 dB(A) for
every surface (e.g. 2 corner walls cause an increase of 6 dB(A);
• install suitable vibration-damping supports under the unit to avoid
transmitting vibrations to the building structure;
• rigid frames may be installed on the top floor of the building to
support the unit and transmit its weight to the load bearing structures of
the building;
• carry out all water connections using elastic joints. Pipes must be
firmly supported by solid structures. If the pipes are routed through
walls or panels, insulate with elastic sleeves.
○ If there are any structural vibrations in the building (after the unit
has been installed and has started to run) which provoke such strong
resonance that noise is generated in other points of the building, consult
a qualified acoustic technician for a complete analysis of the problem.
II.3 OPERATION AND ADJUSTMENT
II.3.1 CONTROL BOARD
The control board features a general isolator with door interlock. The
230 V auxiliary circuit power supply and the 12 V control power supply
is shunted internally by the three phase power supply. The layout of
electrical components in the control board is illustrated in Fig. 7 and Fig.
8.
CE1 = microprocessor controller
IA = auxiliary switch
IC = compressor switch
IG = main switch
IV = fan switch
KC = compressor contactor
KV = fan contactor
TR = transformer
IP = accumulation pump switch
KP = accumulation pump contactor
MF = phase monitor
Control board layout on TCAE-TCAES-THAE-THAES 230÷260 units
• Remote Summer/ Winter enablement on THAE-THAES (SEI)
Change parameter H49 (from 0 to 1) and connect the remote
Summer/Winter selector cables between the terminals (33 and 34 on
models THAE-THAES 470÷4160, 19 and 20 on models THAE-THAES
230÷260) on the user interface terminal board.
CAUTION
Open contact: heating cycle.
Closed contact: cooling cycle.
IMPORTANT!
When the unit is switched OFF using the remote
control, E00 is displayed.
• LF-LB lamp remote control
To remote control the two signals, connect the two lamps according to
the instructions provided in the wiring diagram supplied with the
machine.
