The application program Fan Coil-Actuator/1 is available for the Fan Coil
Actuator. Programming requires ETS2 version 1.3a or higher.
The following functions are available:
Additional output
Fan
Valve
HEATING/COOLING
Binary input
The 6 A outputs are available for Fan Coil applications.
Caution
Improper switching will cause destruction of the fan motors.
The technical data of the fan must be observed,
e.g. speed or switching function.
For further information see: Parameter window
The Fan Coil Actuator features relays in each output which are mechanically
independent of the other outputs. Switching noises cannot be avoided due to
the mechanical nature of the design.
The installation location of the Fan Coil Actuator can either be centrally in an
electrical distribution board, or distributed in a Fan Coil unit. Usually, the Fan
Coil Actuator is used in conjunction with a room temperature controller for an
individual room temperature control system. The room temperature
controller sends a control variable which is used to control the fan speeds
via the Fan Coil Actuator.
For control of auxiliary electrical heating,
e.g. in the Winter
Summer transition phase.
A 3 speed fan is controlled alternately with a two-way
connection or with speed switching.
One valve for HEATING and one valve for COOLING are
controlled. The control of the valves can be implemented
as PWM (constant) control or as 3-point control (opening and
closing). The valve outputs are short circuit protected.
Two binary inputs are available. These are used for example,
to monitor the window contact and condensation (dew point).
