It is possible to connect a 2-wire on/off thermostat to the boiler such
as the
Celcia 10
or a power stealing thermostat. The boiler output
can be modulated by an
OpenTherm
system with an appropriate
modulating thermostat such as the
qSense
or the
iSense
.
3.3.6. Regulation of the water temperature
The boiler is fitted with an electronic temperature regulator having an
outlet and return temperature probe. The flow temperature can be set
between 20°C and 90°C. The boiler reduces its power when the set
outlet-temperature is attained. The cutout temperature is the set
heating outlet-tempe 5 °C.
3.3.7. Protection against a shortage of water
The boiler is fitted with a safety device to prevent the shortage of water
based on temperature measurements. By reducing its output when
the water flow rate is in danger of becoming insufficient, the boiler
continues to operate as long as possible. If the flow rate is too weak
ΔT ≥ 50°C or the heating flow temperature increases too much, the
boiler is locked for 10 minutes, code
5t[09
. When there is no
water in the boiler or the pump is not running, the boiler goes into
safety shutdown, code
e[10
at ΔT ≥ 70°C.
3.3.8. Maximum temperature protection
The overheating safety device locks the boiler when the water
temperature is too high (110°C), code
e[12
.
