The regulation is achieved by direct control of the burner or with the proportional time controls of a 3-way or 4-way motorized mixing valve. The outside and water delivery temperatures are monitored by the appropriate sensors. The temperature values are transmitted to the control unit, which responds to a previously set program and determines the value of water delivery temperature required by the system to maintain always constant the set ambient temperature. STANDARDS AND HOMOLOGATIONS Complies with the law 373, law n.10 dated 9 of January 1991 and D.P.R.412 dated 26 of August 1993. In conformity with EN 60730-2-9; EN 60730-2-7 standards. INSTALLATION Application possibilities: flush, wall or rear panel mounting. FLUSH MOUNTING REAR PANEL MOUNTING WALL MOUNTING FEATURES Potentiometer to select the linearized heating curve (external temperature-water delivery temperature) with adjustable gra- dient from 0,25 to 4,5. Potentiometer for the regulation of the comfort ambient temperature with parallel translation of the heating curve. Potentiometer for the regulation of the economy ambient temperature with parallel translation of the heating curve. A six-position switch to select the operating program: „„ OFF „„ antifreeze „„ always reduced „„ ON „„ night reduced/day comfort (automatic) „„ night antifreeze/day comfort (automatic) Switch for selecting the adjustment type: „„ burner ON-OFF control; „„ proportional-integral control (PI) of the motorized mixing valves with completely electronic feedback. Potentiometer to regulate the stop delay of the circulation pump. Indicator light. Quartz clock with charge reserve of 100 hours. Transparent protection cover. Unit weight 1,02 Kg. A Indicative diagrams of the water delivery temperature as a function of the external temperature. B Circulation pump stop regulation, with a delay of up to 60 minutes. C LED lights indicating valve movement (valve opens or closes); when lights are off the valve is stopped. D Command for the daytime ambient temperature control. E Command for the nighttime ambient temperature control (reduced regime). F Command for the selection of the heating line shown in the Diagram A. G Switch for selecting between the burner control and the motorized mixing valve control. H A six-position switch to set: OFF ALWAYS ANTIFREEZE: in this position water delivery temperature is kept at least at +5°C regardless of the position of the other controls (with burner on). ALWAYS REDUCED ON automatic 1 automatic 2 I Screw for mechanically fastening the electronic panel to its terminal block. L Quartz clock with daily programming.
