Three remote air sensors with 8 m cable
This accessory is a kit of three remote air sensors to replace the supply air sensors installed inside the unit. Cable
of remote air sensors has a length of 8 m and is screened. Sensor cable ends with a quick connector so that discon-
necting standard sensors and connecting the remote ones is easy.
Remote sensors have to be placed at the intake of the most critical rack, usually the most distant rack from the air
conditioner, in order to monitor supply air temperatures. Fan speed of CyberRow unit is then determined by the dif-
ference of temperature between return air and supply air of the critical rack. When this last temperature is high, the
difference is smaller. Thus, fans speed up to reach the set point ensuring a higher ventilation of the rack.
Humidity sensor
The humidity sensor measures internal humidity giving a proportional signal to the C7000 in order to realize the
following functions:
-display of internal humidity value;
-control of humidification function (when humidification is needed an optional humidifier must be ordered).
Range of measurement is RH between 15% and 90%.
When supplied, the sensor is installed in the unit.
Only for CyberRow type CW
3-way valve
The 3-way valve replaces the standard 2-way valve when the CW unit has to be connected to a chilled water distri-
bution system with fixed flow. The kvs value of the 3-way valve is the same as for the 2-way valve, so pressure losses
are the same as the ones indicated in technical data. Operating limits are the same as for the 2-way valve.
