How to access the installation menu?

Set the selector to Automatic mode, then hold down the + and - buttons for 5 seconds. The first parameter (01) is displayed.

What to do in case of sensor error?

If Err appears on the screen, the internal (position T6) or external sensor is faulty. The control stops. Check connections or replace the sensor.

Can I use this thermostat for cooling?

Yes, if the Cooling function is enabled (parameter 08 = Yes). In cooling mode, the thermostat manages the setpoint temperature (factory 22 °C in Comfort).

How to calibrate the ambient sensor?

After 12 hours of operation, place a thermometer at 1.5 m height in the middle of the room. Wait 1 hour, then set the calibration (parameter 04) to the read value.

Installation and Operation Manual

IMPORTANT!

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

• The Main zone digital programmer 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 Main zone digital programmer is developed to control and manage all installations of water floor heating and cooling equipped with our UFH range thermostat. The temperature in each room is managed the control of actuators mounting on the manifold.

• The controller is normally used in conjunction with a complete connecting box TUFH-MASTER" with or without THeating & 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 thermostats and the 230V 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.
