Description:
After heating the sensor H4-S temperature (55
C) shall be attached to the pump (OUT-B). Pump (OUT-B)
operates only when the temperature H4-S is greater than the temperature of H1-S. Pump H1-P, H2-P, H3-P will turn on
when the temperature H4-S reaches 50
C and turn off when the temperature H1-S falls below 25
C.
Boiler (5) turns on
when the temperature measured on the sensor H1-S is below the preset temperature
.
On the valve actuator (6) is given an
electrical voltage when the temperature measured on the sensor H5-S falling below 55
C (loading upper buffer).
A valve
actuator (6) is turned off when the temperature measured at the sensor H5-S rises above 55
C (loading throughout the
volume of buffer).
H5-S sensor activates an alarm if the exhaust temperature exceeds a critical value.
