Before starting work the installer should carefully read this Installation & Operation Manual, and make sure all instructions contained therein are understood and observed.

The thermostat should be mounted, operated and maintained by specially trained personnel only. Personnel in the course of training are only allowed to handle the product under the supervision of an experienced fitter. Subject to observation of the above terms, the manufacture shall assume the liability for the equipment as provided by legal stipulations.
All instructions in this Installation & Operation manual should be observed when working with the controller. Any other application shall not comply with the regulations. The manufacturer shall not be liable in case of incompetent use of the control. Any modifications and amendments are not allowed for safety reasons. The maintenance may be performed by service shops approved by the manufacturer only.
The functionality of the controller depends on the model and equipment. This installation leaflet is part of the product and has to be obtained.

APPLICATION

The UFH thermostat is developed to control and manage actuators mounting on the manifold.
The thermostat is normally used in conjunction with a complete connecting box "UFH-MASTER" with or without "Heating & Cooling module" to connect all electrical & hydraulic components of the installation like a circulation pump, actuators...
The controllers have been designed for use in residential rooms, office spaces and industrial facilities. Verify that the installation complies with existing regulations before operation to ensure proper use of the installation.

SAFETY INSTRUCTIONS

Before starting work disconnect power supply!

All installation and wiring work related to the controller must be carried out only when de-energized. The appliance should be connected and commissioned by qualified personnel only. Make sure to adhere to valid safety regulations.
The connecting boxes are neither splash- nor drip-proof. Therefore, they must be mounted at a dry place.
Do not interchange the connections of the sensors, actuators and the 24V connections under any circumstances! Interchanging these connections may result in life endangering electrical hazards or the destruction of the appliance and the connected sensors and other appliances.

OFF: - 2°C during the night Example of use: for bed room, during the night you need to cool this zone ON: +2°C during the night Example of use: for living room, during the night you don't need to cool this zone

How to use your thermostat

Anti Freeze mode: (Manual mode)

Simple installation without main zone programmer:
The antifreeze temperature (7°C) will be maintained in the room all the time.
Installation with main zone programmer: (with or without Heating and Cooling function)
In heating mode: (Winter)
The antifreeze temperature (7°C) will be maintained in the room all the time.
In cooling mode: (Summer)
The thermostat will be switched Off.

REDUCED operating mode: (Manual mode)

Simple installation without main zone programmer:
The reduced temperature will be followed all the time. (Setting temperature minus 2°C)
Installation with main zone programmer: (with or without Heating and Cooling function)
The reduced temperature will be followed as described below:
In heating mode: (Winter)
The reduced temperature will be the setting temperature minus 2°C.
In cooling mode: (Summer)
The reduced temperature will be the setting temperature minus or plus 2°C.
(See the configuration switch part "Switch N°2" for more explanation).

Automatic operating mode:

Simple installation without main zone programmer:
The setting temperature will be followed all the time.
Installation with main zone programmer:
(with or without Heating and Cooling function)
In this mode your thermostat will follow the program (Comfort or reduced) and order (Heating, cooling, Anti freeze, holiday...) of the main zone programmer.

How to caliber and limit the setting range

If your thermostat needs to calibrated, make these operations:

Put a thermometer in the middle of the room at 1.5 Meter distance of the floor.
Wait 1 hour to be sure that your thermostat shows the correct temperature.
Remove the setting button by pressing gently outwards with a narrow screwdriver between the button and the cover. (pay attention to avoid setting button rotation)
Remove the internal wheel from the button. (Figure 1)
Put the internal wheel alone on the thermostat. (Figure 2)
You can now put the setting button on the thermostat, while making corresponds real room temperature (showed by the thermometer) and thermostat indexer.

If your thermostat needs to be limited, make these operations:

Set the setting button on the middle of the new setting range.
Remove the setting button by pressing gently outwards with a narrow screwdriver between the button and the cover.
Remove the dial pins and put in the desired holes to limit the setting range of the thermostat. (Figure 3 et 4)
You can now put the setting button on the thermostat.
