Boiler, buffer tank, mixed circuit, DHW (Hy0403p)

Boiler, buffer tank, mixed circuit, DHW (Hy0403p)

Product Description

Outdoor temperature-compensated flow temperature control for radiators, convectors or low temperature heating circuits. Hot water control. Integrated differential temperature control for controlling a switching valve for buffer storage. Burner control for demand-based control of all boiler types (one-stage).
Note: System no. 403 means that certain parameters must be set for this application to function.

Mixed heating	1 circuit
Domestic Hot Water	2 pumps
Boiler	1-stage
Solar	for heating
Buffer	charge control
Solid fuel	yes

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.

Boiler control

Single stage boiler control on/off or OpenTherm
Boiler is only used in case the buffer cannot provide the required temperature

Heating circuit

Time switch for daily, weekly and holiday programs for heating circuits
Optimisation of switch-on times
Caretaker function, frost protection function
Outdoor temperature-compensated heating circuits, 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

Buffer tank

A differential temperature control function does switch pump on VA2 to on if temperature at VE2 is higher than on KSPF sensor

Combination

Combination option of up to five freely-selectable SMILE controllers

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.
