All of the GLOBAL units produced without controller, will have no electrical cabinet nor will they be
equipped with a main power switch.
•
All of the GLOBAL units produced without controller, will have no temperature sensors
•
All of the GLOBAL units produced without controller, will be equipped with their heat recovery actuator.
This actuator will be a linear actuator for units equipped with a plate heat exchanger (PX). The linear
actuator will have to be controlled with a 3-point (PWM) control signal. The power supply is 24VDC / 6A.
•
All of the GLOBAL units produced without controller, will be equipped with their heat recovery actuator.
For units equipped with a rotary heat exchanger (RX), this will be an EC stepper drive. The stepper drive will
have to be controlled with a 0-10VDC control signal. The power supply is 24VDC / 6A.
•
The fans are to be connected to a mains power supply; the fan speed (RPM) will have to be controlled with
a 0-10VDC control signal. The 0-10VDC control signal can be connected to the supplied fan control cable.
The electrical connection box is not included.
•
For units equiped with a rotary heat exchanger, a rotation monitor is factory fitted. The sensor is normally
open. Max.48VDC/0,5A. Impedance: 150 mOhm.
•
When the unit is configured with dampers, the dampers will not be factory fitted with actuators.
•
When the unit is configured wit a hydraulic coil, the motorised 3-way valve will not be included.
•
Electrical pos- and preheating coils will only contain the electrical heater elements. Controls and
overheating protections are not included.
•
No frost protection is included on any of the heat exchangers.
•
The operating range is -20°C ... +50°C
•
The EN1886 classification is T3 / TB2 / F9 / L2 / D1. An optional T2/TB2/F9/L2/D1 classification available.
