Setting the volumetric flow rates / hydraulic alignment between mixed and unmixed circuit:
see Fig. D3
The necessary volumetric flow rate for the unmixed heating circuit results from its heat requirement. The necessary flow volume for the mixed
heating circuit and the required pump level of the Thermix pump are to be taken from the enclosed table in accordance with the heating
requirements.
Requirement for presetting both volumetric flow rates:
1. All radiator valves in the unmixed circuit must be set to maximum flow-rate
2. The injection valve on Thermix is completely open (setting 5 on the thermostat head).
3. The pump on Thermix is switched on.
The flow volume is adjusted on the individual flow meters as follows:
1. Set the established pump level on Thermix pump.
2. Set the volumetric flow rate established for the mixed circuit using the compensation valve.
3. Carry out the fine-tuning of both compensation valves until the stated volumetric flow rates are set.
Should there be an increase in the head load/demand, set Thermix pump to the next highest level and perform the adjustment once again. All
modifications of the heating requirement (e.g. in case of an extension of the floor heating area) require a renewed setting of the volumetric
rates.
