Note 3. A hydraulic bypass is required
to allow pump overrun.
Note 4. This system provides heating
to one zone at a time. To heat more
than one zone simultaneously use
zone thermostats to energise individual
zone valves with a call for heat applied
to CH Call. The boiler will be limited to
responding with a set flow temp (see
page 31). The boiler default setting is
for DHW priority.
Note 5. A Frost Thermostat can be
connected into CH Call
