, where: 1 – boiler, 2 – ecoMAXX
regulator – module A, 3 – ecoMAXX regulator – control panel, 4 – fan, 5 – feeder temperature sensor, 6 -
gear-motor, 7 – boiler temperature sensor, 8 – HUW temperature sensor, 9 - mixer temperature sensor, 10
– temperature (weather) sensor 12 – HUW circuit pump, 13 – mixer circuit pump, 14 – electric servo the
valve, 15 – HUW container, 16 – room thermostat or ecoSTER200, 17 – HUW circulating pump, 27 – return
temperature sensor (does not affect combustion process control), P – electric relay.
As there is not mechanically forced water flow in boiler return circuit - this method of protection of
boiler return circuit from cold water is not efficient. Use of other methods is recommended. To
improve water flow in gravitational circuit of the boiler (the circuit is indicated on the diagram with
a bold line) it is necessary to: (i) use pipes and 4-way valve of large DN value, (ii) avoid using
excessive number of elbows and cross section reductions, and (iii) apply other rules of gravitational
circuit construction - e.g. keeping of gradients, etc. In case the return temperature sensor is of
contact type - provide the sensor with heat insulation to isolate it from the environment and
improve its thermal contact with the pipe by application of thermal paste. Set the preset boiler
temperature at so high value that heat output required to the heating circuit and to heat-up return
water to the boiler is guaranteed.
