IV.a.6) Scheme 6/10Installation 6/10 handles:➔ two collector pumps,➔ two accumulative tanks,➔ one direction of collectors location,➔ additional peripherals.Installation sensors:➔ collector sensor,➔ accumulation tanks sensors.TechAdditional installation options:➔ tank 2 set temperatureThis function is used to set the set temperature of the secondtank, after the collector 2 pump deactivates.➔ maximum temperature of the 2 tankThis option is for declaring the maximum acceptable safetemperature value, up to which the second tank will be allowed toheat itself in the case of overheating the collector.➔ tank 2 hysteresisAfter reaching the set temperature, the auxiliary pumpdeactivates. The pump will activate again after the tank temperaturedrops below the set value by the tank 2 hysteresis value.➔ operation algorithmWith this option, the user selects the operation mode of thepumps. The pumps can operate in the following modes:a) tank priority 1 - first, tank 1 is being heated (only pump 1operates) and after reaching the set temperature, pump 2 activates,additionally heating tank 2.b) parallel operation - the pumps operate independently, each inits own scope (in accordance with the settings) and both tanks arebeing heated (according to the settings) at the same time.➔ Maximum heating time Z2 (the function is enabled only when theoperation algorithm is set as the tank 1 priority ).After switching the circulation to the other tank (when the firstone reaches the setting), this parameter determines how long pump 2will work (if conditions for reactivation of the first pump haven't beenmet yet).➔ Oscillation pause (the function is only enabled when the operationalgorithm is set as the tank 1 priority).After maximum heating time Z2, oscillation pause takesplace (the pump is deactivated), ensuring temperature stabilization. Ifduring such a pause the temperature of the first tank sufficiently- 15 -
