IV.5. Electrical connection and operation of the rotary wheel heat exchanger
IV.5.a. BASIC VERSION
The wheel is factory wired
The automatic operation of the wheel is controlled by two thermostats:
In winter: If the outside temperature is below 18°C (adjustable), the wheel starts to recover the maximum amount of heat.
In summer:
COLD RECOVERY: If the outside temperature is greater than 24°C (adjustable) the wheel starts to recover the maximum
amount of heat.
FREE COOLING: If the temperature is between 24° and 18° (adjustable), the wheel stops to allow outside air to flow in directly
IV.5.b. FIRST PREMIUM version
The wheel is factory wired
Its operation is automatically controlled by the CORRIGO controller and the temperature sensors installed as standard in
our VORT NRG ECR systems
In winter: When there is a request to increase the temperature, the wheel starts and rotates up to its maximum speed in order
to recover heat. In cases where this is not sufficient to reach the set temperature, the heater battery will come into operation.
In summer:
COLD RECOVERY: If the outside temperature is greater than the inside temperature and there is a request to reduce the
temperature, the wheel starts and rotates up to its maximum speed to recover heat.
In cases where this is not sufficient to reach the set temperature, the cooling coil will come into operation.
FREE COOLING: If the outside temperature is lower than the inside temperature and there is a request to reduce the
temperature, the wheel slows down and rotates until it comes to complete stop so as to allow fresh outside air to enter the
building. In cases where this is not sufficient to reach the set temperature, the cooling coil will come into operation.
