3.4. Zone module configuration for additional electrical heater
Complete Verso Pro electrical heater section can be used for zone control function. Since inside of the section there is
already PM board installed, additional zone module is not needed. Cables are connected directly to the PM board and only
SW1 DIP-switches should be configured to indicate zone number (see page 10). If electrical heater will be used to maintain
temperature of the independent temperature zone, additionally it will be needed to connect supply temperature sensor. Do
not change SW2 DIP-switches or any cables that are already connected to the PM board of electrical heater section, since it
is used for heater operation.
