1 Modulating digital controller for heating and cooling series REGI ERED SI EN ISO 00:000 Cert. n FM UNI EN ISO 00:000 Cert. n 000 0/0 G replaces dp 0/0 Function The controller can be used with three-point motorized mixing valves with rotation times ranging between 0 and 0 seconds. It performs both set point and modulating regulation. In the modulating mode, the controller automatically varies the flow temperature depending on the actual value of the system return temperature. This is detected to indicate the instantaneous ambient load. This reduces system operating times and power overloads. The controller is equipped with flow and return temperature probes and a wiring box for an easy use when mounted on the wall. It can also be connected from the back by means of a standard recessed electrical box.

2 Digital controller Operating principle The controller receives the activation signal from the ambient thermostat to start the pump and operate the mixing valve. The controller operates the mixing valve according to two logic approaches, depending on whether the return probe is on or off. Set point regulation: return probe off. Selector ) OFF. In this case the flow temperature FT is held constant at the value set using the selector ) for both heating and cooling. The setting is shown on the display ). Modulating regulation: return probe on. Selector ) ON. In this case the flow temperature FT is modified as a function of the temperature measured by the return probe RT. This keeps under control the actual thermal efficiency of the slab and as a consequence the ambient thermal load. This thermal response time of the system is thus reduced to a minimum. RT set = FT set - % (FT set - 0 C) FT calculated = FT set + (RT set - RT) 0 The front panel contains the following functions: ) Three-digit LCD showing: measured or calculated temperature and settings of the delays programmed in the system. Temperature range displayed: 0 C with 0, C resolution. ) Controller function selector ON/OFF. ) Mixing valve on opening: LED on. ) Mixing valve on closing: LED on. ) Selector for setting flow temperature.

C Example: FT set = 0 C RT set = 0-0, (0-0) = C FT calculated = 0 + ( - RT) The new FT value calculated is shown on the display ) highlighted a side bar. Each time the FT is calculated, the measured FT is displayed for s, after which the new calculated FT is shown. Changes to FT stop when the RT reaches the RT set.

4 Control of relative humidity When the controller is used for cooling, the relative humidity probe must be used. The function of this probe is to detect the maximum relative humidity limit in order to prevent the formation of condensation in the cooling slab. It is set for RH = 0 %. When this level is reached, the following operating state is set: pump ON, mixing valve closed. Connection of the humidity probe The humidity probe is connected to the controller through a special transformer and converter. Testing the humidity probe The functioning of the probe must be checked at the start of each cooling season by placing a damp wad of cotton wool on the surface; this should cause the mixing valve to be switched off and switch on the red LED point on the front of the control panel. Location of the humidity probe The humidity probe is located at the point where humidity is most likely to form which will depend on the system design. It is positioned with the carbon printed surface facing upwards as in the following diagrams.
