6. CONTROLS
Usage of automatic control dedicated to the air water heaters of Reventon
Group gives great possibilities of adjusting the efficiency of the heater
in different, depending on needs, degree of its operation automation.
We can offer the following:
is used to regulate devices equipped with 3-stage fans. It has a 3-stage speed
control and built-in thermostat switches the device of automatically
when the preset temperature is reached. In addition, the unit controls
the operation of the actuators installed on the control valve
.
Voltage/ Frequency: 230 V AC / 50 – 60 Hz
Maximum current output: 3 A
Temperature range: 10°C - 30°C
Operating mode: continious or thermostatic
Control accuracy: <1°C

is used to regulate devices equipped with 3-stage fans. It is an advanced
controller with many functions i. a. operation in heating, cooling or mixed mode,
programmable mode, valve control, automatic selection of the fan speed.
Together with the controller an external sensor is provided, which allows to read
the temperature in the required place, even remote from the controller.
In addition, the device can be integrated with the BMS building control system
(using the MODBUS communication protocol).
Voltage/ Frequency: 230 V AC / 50 – 60 Hz
Maximum current: 5 A
Operating temperature range: 0 - 45°C
Regulation range: 5°C - 35°C

d esigned to change the single-phase fan's speed voltage controlled in industrial
supply and heating systems. It is available in several versions. The selection
of the appropriate model depends on the number of the devices that have
to be connected to the to one regulator – the total intensity of the connected
devices cannot exceed the maximum current flow of the regulator.

- before service or exchange of the device it is obligatory to cut off the current
supply
- do not limit or cover the inlet and outlet of the device
- do not install, service the device with wet hands or barefoot
- the device should be kept out of reach of children and animals
- the device does not consist of the anti-frost protection - the temperature
in the room, where device is installed, should not go below 0°C; if such situation
could take place empty the device out of water
- after the turn off, the elements of device may be warm
-after operating time of the device, please utilize it concerning the local norms
and regulations
- it is recommended to clean the device periodically (at least once per month ):
ź
heating coil blow with compressed air
ź
fan casing and blades clean from dirt
- for installation of the device in a room where is high dust concentration,
the periodic cleaning should be performed much more often, not allowing
the heat exchanger to 'clog’
- failure to comply with cleaning obligations may have a negative effect
on technical parameters of the device
and lead to loss of warranty
- i f the device is not used for a longer time disconnect the power supply
- air stators of the device have to be open in at least 30% before first start:
ź
standard version - opening of air stators must be done by two hands in parallel
ź
version with diffuser 360° - air stators of diffuser 360° must be done by two
hands to the outside
ź
version with confusor - the outlet do not have air stators which must be open
- using diffuser 360° or confusor causes decrease of device airflow of around
10% and consequently reduction of its heating capacity of about 5%
