14 . Connection of boilers D14P, P14, D15P, P15, D20P, P20, D21P,
P21, D25P and P25 with a buffer tank with solar heating
for burner control on the basis of TS, TK and TV sensors
(automatic sensor switching function), function of controlling
the solar pump based on TSV and TS temperatures
INFO - The TV, TK and TS sensors on the buffer (accumulation) tank with solar heating (TV
and TS sensors (boiler accessory)) , TSV temperature sensor located in the solar panel, all
connected directly to the burner. The system does not require any AD02 or AD03 modules,
the solar pump is electrically connected directly to the terminal board of the boiler, where it
is controlled directly from the boiler through the R2 reserve. Except for boilers D20P, P20,
where the AD03 module (boiler part (accessory)) is used only for controlling the exhaust fan
(module AD03 – LA clamp).
Required accessories (not part of the burner): one KTF 20 sensors, AGF3 solar panel sensor up to
400 °C or VFF00-75P65 up to 300 °C with pocket
System configuration of parameters: S6 = 4, S14 = 14, S15 = 3
(reserve R – parameter S6 controls the fan – only for boilers D20P / P20)
CAUTION - Do not connect the TK sensor placed in the pocket of the boiler to the burner
connector for the D20P and P20 boiler (free cable in the rear part of the boiler). Instead of,
connect the TK (Ts2) sensor located above the solar exchanger in the buffer (accumulation)
tank (see diagram).
Pump in the boiler circuit is controlled via the directly installed thermoregulator from the boiler panel.
