8.3.4 Electric reheater RXB39.1 (DC 0...10 V plus relay)
• DC 0…10V (output YC1):
The controller is equipped with a 0…10V output for controlling the electric reheater.
• Relay (Q13, Q14):
An additional relay is provided for switching the power on and off
(max load 10 A / 1.8 kW ohmic).
The relay is activated when the demand exceeds 4% and it is deactivated when the
demand is 0% (hysteresis).
This functionality can be enabled and disabled (P099, see page 104).
The controller output of the electric reheater is disabled locally via a safety thermostat
and / or the air circulation input connected to one of the digital inputs.
The safety and air circulation inputs and the way they operate can be configured with
the tool (see "Digital inputs", page 142).
– When the safety thermostat or the air circulation sensor trips, a corresponding alarm
is generated and is transmitted via the communication object Alarm (see page 150).
– When the safety thermostat sensor trips, the fan remains on for the minimum on
time, then it stops if no other sequence (water) is active.
– When only the air circulation sensor trips, the fan output signal remains on.
The min. fan speeds for heating Comfort, Precomfort, Economy and Protection
(P153, P156, P157 and P158, see page 129) must be set to a value that guarantees
that the full heat of the electric heater can be dissipated.
