3 GENERAL FEATURES MySystem is designed to manage heat pump on/off, a modulating valve and an integrative / replacement boiler MAIN FUNCTIONS AND EQUIPMENT: Switches unit on/off. Displays water valve temperature Displays outdoor air temperature Switches boiler on/off. Modulating valve control The control panel includes: 3 RG REV.01

4 LCD display keyboard LCD DISPLAY Evaporator outlet water temperature 2 Outdoor air temperature 3 Modulating valve setpoint Mysystem on Mysystem off Operation mode: Cooling. Operation mode: Heating. Alarm present Heat Pump active Celsius / Fahrenheit visualization Boiler active Backlighting turns on whenever any button is pressed and turns off automatically about 2 minutes after the last key was pressed 4 RG REV.01

5 KEYBOARD: ON/OFF key: Switching the unit on/off. When changing user parameters, it allows to return to normal operation. the key does not work when the digital input ON/OFF is active UP and DOWN keys: changes setpoint. used when changing parameters to select the parameters or to change values. SEL key: accesses parameters change / selection confirmation MODE key: Selection of Heating / Cooling operation mode (2 different setpoints for modulating valve) ECO key: cancel parameter change Active key combinations: Access to parameter configuration procedure Displays opening valve % Change Celsius / Fahrenheit visualization 5 RG REV.01

6 MAIN LOGIC MySystem can manage an heat pump and an integrative/replacement boiler at the same time acting on digital contacts. Heat pump switching off and boiler switching on are individually settable on external air threshold. Choosing setpoint equal to differential allows an integrative logic, otherwise, crossing the two phases, allows a replacement logic. Modulating valve regulation works on water probe reading and consists of a dead zone around setpoint with no regulation, the next zone has a regulating step (ual PErC) and a modulating time (ual tiπe) settable by parameter. Regulations zones are settable by dead zone parameter ( Zn dead ) and modulating valve differential ( ual Diff ) parameter. Outside that area regulation is fast with step: (ual PErC) * (ΠuL FACt) And time: (ual tiπe) / (diu FACt) ACCURATE REGULATION NO REGULATION ACCURATE REGULATION FAST REGULATION FAST REGULATION SET - DIFF SET ZN/2 SETPOINT SET + ZN/2 SET + DIFF 6 RG REV.01

8 use the keys to change the value of the display to the value of the password 10, then press. If correct, you can access the parameters use the keys to scroll the various parameters (see Parameter List described above) press to activate the parameter change (the value will flash) use keys to change the value press to save the new value set or to cancel the change once the concerned parameters have been changed, press the key to exit the procedure 8 RG REV.01

12 WALL INSTALLATION OF CONTROL NB: for wall installation, it is recommended to use an electrical box behind the control to house the wires. NB: before installation, carefully remove the protective film on the display. Film removal may cause dark halos to show up on the display which will disappear in a few seconds and are not a sign of a defect. Instructions for wall installation 1. Remove the control's closing screw. Fig If a 503 electrical enclosure is used, pass the cables through the slot at the bottom of the control and use the holes provided for fastening. Fig Otherwise drill holes in the wall where you would like to install the control, matching the fastening slots (5 x 8 mm) at the bottom of the control. Pass the cables through the slots at the bottom and fix it to the previously drilled holes in the wall with screws. 12 RG REV.01

13 Fig Perform the electrical connections on the terminal board following the relative electrical layout. 5. Close the control fastening the screw removed in point RG REV.01
