Channel
Address for communication with SMO 10/VVM 300/EVP
500.
A1
When connecting to VVM/EVP 500 this channel should be
on 1.
When connecting to SMO 10 this must be selected so that
each F2025 in the system receives a unique address (1 – 9)
for communication with SMO 10.
For example 3 x F2025 in the same system are allocated
the addresses 1, 2 and 3. The F2025 that produces hot
water should be set to 1.
Max return temperature. When the return temperature
reaches the set value the compressor stops. The value is
adjustable between 25 and 50 °C. Factory setting 48 °C.
A2
With SMO/VVM/EVP 500 connected this menu cannot be
changed, it is locked at 50 °C.
Connection difference return temperature. After the com-
pressor is stopped for a high return temperature, the return
temperature should drop by the set value in order to permit
the compressor to start. The value is adjustable between 0
and 10 °C. Factory setting is 4 °C.
A3
With SMO/VVM/EVP 500 connected this menu cannot be
changed, it is locked at 2 °C.
Minimum time period in minutes between compressor
starts. The value is adjustable between 20 and 60 minutes.
Factory setting 20 minutes.
A4
Balance temperature, the set outdoor air temperature when
the additional relay (14) can be activated from channel A6
without affecting compressor operations. Additional heat
relay (14) is activated first after the set time on channel A6.
The value can be set between -20 (set stop temperature,
channel A7) and +10 °C. Factory setting is 0 °C.
A5
Continuous operating time with the compressor before
additional heat is permitted. The value is adjustable
between 0 and 120 minutes. Factory setting 120 minutes.
A6
Stop temperature, the set outdoor air temperature value
when the downtime relay (16) is activated, F2025 stops.
When the stop temperature is set between -7 and -20 °C
the flow temperature is limited linearly from -7 °C / 58 °C
to -20 °C / 50 °C. Factory setting is -20 °C.
A7
Minimum running time, heat production before new de-
frosting is permitted. The value is adjustable between 10
and 90 minutes. Factory setting according to the table be-
low.
