Boiler, buffer tank, mixed circuit, DHW, solar circuits (Hy0404p)
Outdoor temperature-compensated control with buffer tank for one radiator, convectors or low temperature heating circuit. Integrated differential temperature control for controlling a solar system. Burner control for demand-based control of all boiler types. Various variants of hot water priority circuit.
Note: System no. 404 means
that certain parameters must be set for this application to function.
Domestic Hot Water
for DHW, heating
The basic functions are contained in an indestructible program.
All the parameters are predefined with sensible basic settings and allow individual adjustments as necessary. PCs are not required for this.
All the relay outputs can be tested manually.
Sliding boiler temperature control for one-stage boiler
Time switch for daily, weekly and holiday programs for heating circuit
Optimisation of switch-on times
Caretaker function, frost protection function
Outdoor temperature-compensated heating circuit, with room tie-in as necessary
Min./max. limiting of flow temperature
Cooling function - switchover based on outside temperature
Hot water control
Time switch with daily and weekly program for hot water filling pump
Anti-legionella automatic system
Hot water priority circuit
Outdoor temperature-compensated parallel operation only in mixed circuit
The temperatures of the collector (KVLF) and the hot water tank (VE2) are compared. The control unit switches the solar pump on when the collector sensor detects a higher temperature than the tank sensor.
Solar energy is used to fill the hot water tank and the buffer tank.
Combination option of up to five freely-selectable SMILE controllers
Communication takes place over the system bus without additional interfaces
Distance (max. 100 m)
All the data required for the control system is communicated
Remote operation with the wall modules SDW.. also takes place using the system bus
If the required temperatures cannot be achieved within a reasonable time, or sensors interrupt or short-out, then the controller will generate a fault message.
