General Description - Vents PA 01W Operation Manual

The present technical specification is intended for technicians and engineers involved in design,
installation and setup of ventilation equipment automation systems.
The General Operation Guidelines (see. Page 18) are intended for end users.
Following the control unit operation and maintenance instructions is a prerequisite of its trouble-
free operation and long service life.
The automatic control system (Fig. 1) is designed for integrated management and control of
ventilation and air conditioning systems.
The device is enclosed in a plastic casing.
The control unit casing contains automatic equipment circuitry of the as well as control and
protective elements of the power components.
The regulating functionality is implemented by means of a programmable controller. The control
unit is suitable for indoor installation in a dust-free dry environment free from chemical contaminants.
The control unit casing meets IP65 standard (units PA 01 W, PA 02 W and PA 03 W) and IP54
standard (unit PA 04 W) with the top lid closed.
The permissible ambient temperature during operation is from +5 °С to +40 °С.
PD1
PD1 - pressure safety switch.
P1 - remote control.
TE1 - ambient temperature sensor.
TE5 - supply air temperature sensor.
Fig. 1
the electronic aCS automatic control and monitoring unit performs a number of functions
- in particular:
1. Switching the unit electric motor on and off.
2. Selecting the fan speed (3 settings).
3. Air supply fan operation control and monitoring.
4. Maintaining the supply air temperature at the pre-set level by actuating the three-way
valve which adjusts the heat-transfer medium delivery into the heating coils.
5. Protecting the hydronic coil heater against freezing (using the input data from the
downstream air temperature and return water temperature sensors).
6. Monitoring and control over the operation of the circulation pump delivering the heat
transfer agent to the heating coils.
