The primary circulation pump/s must be controlled by the S61 board, or directly
(via “N.O. contact” contacts or 0-10V signal) or indirectly (“OR” use of said contacts
by BMS type external systems). Otherwise, the primary circulation pump/s must be
running permanently.
6.5 TYPE C CONSENT SWITCH
Before making the electrical connections, make sure that work is not carried out on live
elements.
General indications
Check that the power supply voltage is 230 V 1N - 50 Hz power.•
Make the electrical connections as given in the following wiring diagrams.•
Make the electrical connection in such a way that the ground wire is longer than •
the live wires. In this way it will be the last wire to be pulled away if the mains cable
should accidentally be pulled, and will thus guarantee the ground connection.
Electrical safety is ensured only when the appliance is correctly connected to an efficient
grounding system, realized according to current safety regulations. Do not use gas pipes
as grounding.
How to connect the consent switch
You will need: the appliance is not powered electrically (external master power switch
set to OFF)
Connect the permissive (on-off switch or ambient thermostat or timer, etc.) to ter-1.
minals R and W on the appliance’s electronic board as shown in Figure 6.23 Electri-
cal wiring diagram → 70 (detail “CS”).
For the appliance to operate correctly, it is ALWAYS necessary to provide a consent switch.
Do not use the general mains external circuit breaker («GS») to switch the appliance on
or off.
