P Zone ambient temperature sensor
- For zone 2, Floor: mandatory, supplied with the module.
- For zone 1, Floor: required only if the control unit is not placed in a
location that is representative of the temperature in zone 1.
Caution:
In this case, the remote zone 1 sensor must be activated through
parameterisation on the control unit (refer to control’s technical manual).
This sensor is proposed as accessory 70250065.
- Wall mounting: the sensor is designed to be mounted in a "Mosaïc" type
(45 x 45), flush-mounted electrical box (not supplied).
It is to be installed in a location that is representative of the temperature
in the zone.
- The sensor must not be installed in corners, on shelves or behind
curtains, near sources or heat or directly exposed to sunlight.
The unit should be installed approximately 1.5 m above the floor.
- Use a 2-conductor cable for installation, minimum size: 0.5 mm2and max. length: 25 meters.
- To be connected directly on the corresponding zone board (terminals Cand S5).

5 - START-UP
5.1 - VERIFICATIONS
• Ensure that the hydraulic connections are properly tight and that the hydraulic system operates correctly:
- purge of circuits,
- valve position,
- hydraulic pressure (1.5 to 3 bar).
• No leaks.
• Proper machine stability.
• Electrical cables and wires are well secured to their connection terminals. Loose terminals can cause heat build-up on the
terminal board and malfunctions.
• Ensure that the electric cables are properly protected from all sheet metal edges or metal parts that could damage them.
• Ensure that control cables and power cables are properly separated.
• Check that the unit is properly grounded.
• Make sure that no tools or any other objects have been left in the machine.
5.2 - CONFIGURATION / SETTING
• Set the button on the installation's control box to OFF.
• Turn installation and module power on.
• On the control unit, configure the system for the "2 Floor Zones" application (parameter 70 = 2); then check and adapt the
parameterization to the installation conditions (consult the control’s technical manual).
• Check that the setpoint settings of the generator regulator are compatible with the "2 Floor Zones" application.
• Check the position of the zone addressing micro-switches (Z1/Z2), see the diagram in § 7.
Before carrying out any work on the machine, make sure that it is switched off and that access to it is prevented.
Any work must be carried out by personnel qualified and authorised to work on this type of machine.

5.3 - OPERATION
• Check circulator operation in the generator and the operation of the 2 circulators of the module. Adapt the speed of the
circulators in order to respect the flow rates. For the generator, refer to the corresponding installation manual.
Note:
When the system is off, operation can be forced by changing the parameterization:
- of zone 1 (accelerator on and control valve open) with parameter 65,
- of zone 2 (accelerator on and control valve open) with parameter 66,
- of the generator with parameter 67.
• Check that water is properly circulating in the installation (valve position).
Note:
The mixing valves of each of the module's floor zone outgoing lines are delivered in full open position
(position “1”).
They are equipped with a “3-point” motor for 230 VAC controlled by the zone board:
- Y1 = open control signal,
- N= neutral (common),
- Y2 = close control signal.
When off, it is possible to open the valves by actuating the motor using a 3 mm Allen wrench.
• Purge the installation. Check the bleeders located in the 2-zone module and heating module.
CAUTION:
An incorrect purge could result in malfunctions and damage to the heater of the heating module.

6 - MAINTENANCE INSTRUCTIONS
• Before doing any work on the installation, make sure it is switched off and all power supplies locked out.
• Any work must be carried out by personnel qualified and authorised to work on this type of machine.
IMPORTANT NOTE
• Water flowrate: The module's outgoing water lines
are equipped with 1/4 SAE pressure taps at the inlet
and outlet of each circulator, to enable the pressure
loss to be measured using a hydraulic pressure
gauge. Use the following circulator curves below
(circulator SXM 32 - 55) to find the water flowrate.
• Start the system in the desired operating mode using the control box button (consult the control’s technical manual and the
control box user's guide).
Caution:
At the end of testing and before starting the installation, the forced configuration must be deactivated
and parameters 65, 66 and 67 returned to zero.

GENERAL MAINTENANCE
All equipment must be properly maintained in order to provide optimum performance over time. Faulty maintenance can result in
the cancellation of the product guaranty. Depending on the products, maintenance operations consist in the cleaning of filters (air,
water), internal and external exchangers, casings, and the cleaning and protection of condensate tanks. Treating odours and the
disinfection of room surfaces and volumes also contributes to the cleanliness of the air breathed by users.
•Perform the following operations at least once per year (the frequency of operations depends on the installation and
operating conditions):
- Check the composition and condition of the coolant.
- Check operating points and setpoints.
- Check the safety devices:
- Dusting of electrical boxes.
- Ensure that all electrical connections are properly tight.
- Check the ground connections.
- Check the hydraulic system (cleaning of the filter, water quality, purge, flowrate, pressure etc.).
