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 temperature
(parameter S4.10) independent of the time program.
If solid fuel boiler temperature exceeds the maximum boiler temperature - parameter
S5.13, the maximum allowed d. h. w. temperature (parameter S4.3) is set for required d .h.
w. temperature.
D. h. w. warming in storage tank with integrated heat pump
In this case, a special operation mode of d. h. w. control is activated by setting the param-
eter. S1.4=8 (for sensor T1) or S1.5=11 (for sensor T8). Install a room sensor in the room,
where the heat pump is located, and connect it to the T1 or T8 terminals. Controller will
block the d. h. w. warming with boiler if the heat pump room temperature is higher as set
with parameter S4.11.
D. h. w. warming with solar collectors
The basic operation of the solar collectors system is determined by switch-on difference,
switch-off difference and minimum temperature of solar collectors - parameters P6.1, P6.2
and P6.3.
D. h. w. is warmed up to the requested temperature, set with parameter S4.10.
If d. h. w. is warmed and the temperature of solar collectors exceeds the maximum tem-
perature of solar collectors - parameter S6.1 and S6.2, d. h. w. warming is allowed up to
the maximum d. h. w. temperature - parameter S4.3.
D. h. w. warming is switched off unconditionally, if the d. h. w. temperature exceeds the
maximum temperature - parameter S4.3, or if solar collectors temperature exceeds the
maximum temperature - parameter S6.3.
When d. h. w. is warmed with solar collectors, you can set the liquid fuel boiler operation
mode with parameter S6.6:
S6.6= -1, simultaneous operation of both heat sources.
S6.6= 0 ÷ 600, the boiler will be switches on with set delay after deactivation of the solar
system. Parameter value sets minutes of delay.
D. h. w. warming with an electric heater
You can reprogram the output to control the electric heater for d. h. w. warming by setting
the parameter S1.11=3 or S1.12=4.
D. h. w. will be warmed up to the requested temperature according to the 2nd time program
for d. h. w. warming.
To control the electric heating body, a power relay and a thermal fuse must
be connected.
Priority of d. h. w. warming over room heating
With parameters P4.2 and P4.3 you can set the priority of d. h. w. warming over room heat-
ing. By direct heating circuit is suggested to set priority to d. h. w. warming.
Return cooling of domestic hot water (Recooling)
If d. h. w. exceeds with the maximum temperature - parameter S4.3, a cooling of the d. h.
w. into the boiler or into the solar collectors can be activated - parameter S4.4.
