NOTE
The following pages about thermostats, additional
heat, common alarms and downtime, do not apply
when F2015 is controlled by SMO 10/VVM 300.
Thermostat control
You can use a basic thermostat or a closing potential-free
contact to switch the compressor on and off. This thermostat
should be of the breaking type (NC) when the set temperat-
ure has been reached. The contactor should be potential
free.
Connection of the single step thermostat is made as set out
in the picture below.

Additional heat / Downtime
F2015 is equipped with a potential free contactor intended
for additional heat. Max 250V 2A.
The setting of the outdoor temperature (balance temperature)
when the additional relay is activated is made on channel
A5, see the section “Control - Channel description”.
External additional heat: connected via the additional relay
terminal X201 (14).
Conditions for connecting additional heat:
႑
the outdoor air temperature should be lower than the
set balance temperature (channel A5).
႑
The compressor must have been operating for the minim-
um period that can be set in channel A6. Defrosting is
included in this time.
If the outdoor air temperature drops down to a level below
the set value, stop temperature (downtime), in channel A7,
compressor operations are blocked and all heating must take
place using the external additional heat via the downtime
relay terminal X201 (14). This function is also activated when
F2015 is deenergized.
If the outdoor temperature exceeds 35 °C compressor oper-
ation is blocked and downtime is activated.
The connection to the additional relay is made as set out in
the picture below.

Max load across the relay contactors is 250V 2A.
During operations without the need of the additional heat
or downtime the relay contactors are closed between NO
and COM.
Additional heat and downtime are acquired between NC
and COM.
The contactors are drawn in the deenergized state.
Additional and downtime relays are activated during normal
operating conditions for F2015. Both relays are deactivated
in the event of operating disruptions.

External indication of main alarm
F2015 is equipped with a contactor for external indication
of common alarms. The function becomes active with all
types of existing alarms. Max. load across the relay contactors
is 250V 2A.
Make the connection for external indication of the main
alarm as set out in the figure below:
