Solid fuel boiler, buffer tank, mixed circuit, DHW, solar circuits (Hy0405p)

Outdoor temperature-compensated flow temperature control for radiators, convectors or low temperature heating circuits. Integrated differential temperature control for controlling a solar controller. Operation of a solid fuel boiler with constant return temperature control for optimum tank protection. Hot water priority circuit.
Note: System no. 405 means that certain parameters must be set for this application to function.

Functions

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.

Solid fuel boiler

The solid fuel boiler is protected against corrosion and "shining soot", according to its boiler temperature using constant return temperature control. The sensor (PF) works as a joint flow sensor for the buffer tank and the solid fuel boiler.

Heating circuit

Time switch for daily, weekly and holiday programs for each heating circuit
Optimisation of switch-on times
Caretaker function, frost protection function
Outdoor temperature-compensated mixed circuit/direct heating circuit, as required with room tie-in
Min./max. limiting of flow temperature
Cooling function - switchover based on outside temperature

Hot water control

Solar control

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. The solar system is used to fill the hot water tank and the buffer tank.
Solar energy is used to fill the hot water tank and the buffer tank.

Combination

Communication

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

Fault message

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.
