Condensate tank heating cord control
:
- Actuated if the outside temperature (probe
SD4
) drops below 0°C (regardless the unit's operating mode). The "heating
element" indicator light (
8
) illuminates.
•
Operating mode selection
:
- The regulator is configured in the factory for On/Stand-by control using an external contact.
- In stand-by mode, the circulating pump continues to function.
Note:
It is possible to shut the unit down completely (circulating pump stopped) by pressing the
ON/OFF
button (
1
).
- This configuration is adapted to system applications,
- For other applications, complete shutdown (“
OFF
”) by remote contact (instead of
stand-by
) can be achieved by
modifying the configuration.
In the "
CnF
" configuration section, change the parameter
H20
from
7
(remote stand-by) to
4
(remote
OFF
). In the
case of
remove
"
OFF
" complete shut-down, the display is off. Only the decimal indicator lamp
flashes
.
The stand-by mode is indicated by the extinction of the heating mode indicator lamps.
•
Pre-ventilation
:
- Generally speaking, in order to condition the air heat exchanger, the fan always starts at full speed a few seconds before
the compressor.
•
Anti short-cycle time delays
:
- The compressor control features a time delay system in order to respect:
• a maximum number of starts per hour (10),
• a minimum stop time.
•
Cycle inversion valve
:
- The valve is actuated during defrost cycles.
•
Control hysteresis
:
- See the operating diagrams in paragraph 5.4.
- The factory setting for hysteresis in heating mode is 4k. Modification is possible. To do this, modify parameter
C04
(heating hysteresis) in the compressor section "
CP
".
6 - ACCESSORIES
6.1 - WATER CONNECTION HOSES
• Length 1 m, insulated, female:
- Ø 1” code
70600055
for
PHT 13
and
16.
6.2 - REMOTE CONTROL
• Code
70250055
.
• The functions and display are exactly the same as those on controller.
• The only difference concerns the buttons
and
which are
separated by the “
ON/OFF
” and “
Mode
” buttons.
• Reminder: the parameters are accessed by simultaneously pressing the
“
ON/OFF
” and “
Mode
” buttons.
•
The controller is designed to be installed inside sheltered rooms.
• Connection:
- the control is delivered with a connecting it to the “ECH” controller,
- to extend the link, max. length: 100 meters, use twisted pair shielded
cable with a cross section of at least 0.5 mm
2
(shielding of the ground
on unit side).
CAUTION:
Do not route this cable near power cables.
The operation must take performed with the unit's power supply off
and locked out.
