D. H. W. WARMING
D. h. w. warming with liquid fuel boiler
The d. h. w. is warmed with a time program from controller or room unit. Which program
time is used is set with the parameter S4.12.
With the parameter S4.13 you can set the required d. h. w. temperature for the inactive
time program interval.
If the boiler temperature exceeds the maximum allowed boiler temperature - parameter
5.2, then for the required d. h. w. temperature the maximum d. h. w. temperature is set. -
parameter S4.5.
When the d. h. w. is warmed, the circulation pump BLP is switched off with 2 minutes de-
lay. The circulation pump is immediately switched off, if the temperature difference to the
heat source drops below 3 K.
D. h. w. warming with solid fuel boiler
When a solid fuel boiler is in operation, the d. h. w. is warmed to the required d. h. w. tem-
perature independent of the time program.
If the solid fuel boiler temperature exceeds 82 °C, the d. h. w. is warmed to 72 °C.
In case the solid fuel boiler temperature exceeds the maximum boiler temperature - pa-
rameter S5.9, then for the required d. h. w. temperature, the maximum allowed d. h. w.
temperature is set with parameter S4.5.
D. h. w. warming priority to the mixing circuit
The d. h. w. warming priority to the mixing heating circuit can be set with the parameter
S4.1.
D. h. w. warming priority to the direct circuit
D. h. w. warming priority to direct heating circuit is default set with parameter S4.2. If the
d. h. w. is not warmed in 50 minutes, then for 20 minutes the room heating is activated,
after that the d. h. w. warming continues.
D. h. w. warming with sun collectors
Operation of the solar system is defined with switch on difference (Sun collectors differ-
ence), switch off difference - parameter S4.8 and the minimum sun collectors temperature
- parameter S4.9.
When the d. h. w. temperature rises close to the maximum d. h. w. temperature - parame-
ter S4.16 and the sun collectors temperature is lower then the protection temperature for
solar collectors - parameter S4.10, the circulation pump KTP is switched off.
If the sun collectors temperature exceeds the protection temperature for sun collectors -
parameter S4.10, the circulation pump KTP is switched on again and it switches off, when
the sun collectors temperature drops for 10 K below the protection temperature.
The circulation pump KTP is switched off unconditionally, if the d. h. w. temperature ex-
ceeds max d. h. w. temperature (S4.5) or if sun collectors temperature exceeds max. tem-
perature S4.14.
When and how the d. h. w. is warmed with the liquid fuel boiler and with the sun collectors
is set with parameter S4.11:
S4.11=-1, simultaneous operation of both heat sources is enabled,
S4.11=0 ÷ 600, boiler switches on with a delay (in minutes), after the sun collectors
operation
