The conditions that cause the WEST manifold pump to
activate are as follows:
S_4≥TABC+
Hysteresis value
e
S_4≥S_2+
Hysteresis value
The following are the conditions that cause the collector pump
to shut down:
S_4<TABC
or
S_4<S_2
Where is it:
S_1: Temperature detected by the collector probe (EST).
S_2: Temperature detected by the boiler probe.
S_4: Temperature detected by the collector probe (WEST).
TABC: Temperature set in installer parameter P2. ABC function
hysteresis value: 3.0 ° C (fixed not modifiable)
The only active controls will be those relating to maximum
temperatures and safety.
