  • Page 41: Functions For Boiler Control

    FUNCTIONS FOR BOILER CONTROL The functions for boiler control are accomplished via the potential-free relay contact which is connected accordingly to the relevant interface of the heating boiler. The individual functions are assigned the following priorities: Anti-legionella priority 1 11 14 12 recharge suppression priority 2 reheating...
  • Page 42 FUNCTIONS FOR BOILER CONTROL Disable recharge The effi ciency of a solar plant increases as the recharge of the tank from the boiler decreases. Consequently, „disable recharge“ means that recharging of the water tank is blocked by the boiler. Recharge suppression during solar yield The recharge function of the heating boiler is suppressed while a solar circuit pump is operating.
  • Page 43 FUNCTIONS FOR BOILER CONTROL Note! For boilers without control input, the functions for boiler control can be accessed by the simulation of temperature values. To enable reheating or anti-legionella functions, the corresponding boiler temperature must be increased at the boiler control. The differential temperature controller smart Connection provided at the Sol regulates the boiler control functions by...
