Installation and connection
1. Install electrical pre-heater (ELH) at least 100 mm dis-
tance from the unit in the outdoor air duct. Relay (RL) is
used to control the pre-heater. Connect the relay to
any free digital output on the connection board (CB).
2. Connect pre-heater (ELH) and the power supply to the
relay (RL). A circuit breaker (BRK) is not included in the
package and must be ordered separately. It must be in-
stalled in the circuit.
3. Install a duct temperature sensor (OAT) before the
electrical pre-heater on the outdoor side of the unit
and connect it to any free Analog Input on the connec-
tion board (CB).
