RHOSS ELECTA Series, Instructions For Use Manual, Page: 297 / 344

1. Remore On/Off: I morsetti 7-8 devono essere cortocircuitati per consentire l’accensione dello INTERFACCIA UTENTE e quindi della ELECTA.
2. In W.S.: The temperature sensor “In W. S.”, for the return water from ELECTA must be disconnected from the PCB.

water delivered to the radiant system.
4. Set Point 2: A switch needs to be set up between terminals 13-14 , which enables water production to the second set point when it is closed,
suited for fancoil operation.
5. Out Signal 0-10Vdc: Mixing valve cables Y and G0 are connected between ter and - (0-10V modulating signal).
6. Power Supply 24V 6VA: Mixing valve cables G0 and G are connected between terminals 26-27 (24V 6VA power supply).
NOTE: cable G0 of the mixing valve is shared by terminals – and 26, which can accordingly be short circuited.
7. Out Pump 2: The pump for the radiant system must be connected between terminal I and the neutral of the terminal block.
8. Either the KCTR can be used as a room thermostat, or a simple thermostat set up between terminals L-K for systems that only have pump P1, or
that have the phase on terminal J for systems where the radiant area is served by pump P2.

System), on the PCB-TERMINAL BLOCK :
0: STANDARD. Temperature signal from the sensor installed on the
water return. The “In W.S.” connector must be
connected to the PCB-TERMINAL BLOCK. 1: NTC_RADIANT. The
temperature of the water
delivered to the radiant system is measured (sensor duly set up
by the installation technician). The “In W.S.” connector must be
disconnected from the PCB-TERMINAL BLOCK. The temperature is
measured on the storage, for the advanced control of an additional
generator (sensor duly set up by the installation technician). The “In
W.S.” connector must be disconnected from the PCB-TERMINAL
BLOCK.
