General VAV-kit | 1
1 General VAV-kit
The VAV duct pressure control kit is used for VAV control of Air Handling units. Included in the kit are: 2 pcs of pressure
transmitters PTE (Pressure Transmitter Extract), PTS (Pressure Transmitter Supply), pressure outlet, tubes, electrical ca-
bles (4m) and installation instruction.
The pressure transmitters max working range is 0...1250 Pa.
2 Warnings
Danger
• Make sure that the mains supply to the unit is disconnected before performing any maintenance or
electrical work!
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
• Beware of sharp edges during mounting.
3 Mount pressure transmitters
The pressure transmitters need to be mounted in the supply and extract air ducts (figure 1) and connected according to
external connections, chapter 6.
Supply duct, connect the tube from the supply duct to +. Extract duct, connect the tube from the extract duct to -.
Connect the electrical cables to the electrical connection box.
