The Fans

Description

The Fans are used to control multi speed fans like ceiling sweep fans, etc…

The function can control the fan speeds with a maximum of 4 speed (+OFF). This paragraph considers the Fans which are controlled by a Fan Interface (TDS13522). For Fans controlled by independent relays, please consult 'the fan (Ceiling sweep) function'.

The different available parameters

Within the function:

Name Outputs
See chapter ‘Assigning TELETASK Outputs’.
Speeds
This determines the number of speeds available for this fan. Must be compatible with the capacitor(s) of the fans supplied by the vendor of the fan. There are 1 speed (+OFF) up to 4 speeds (+OFF) available.

Working of an interface

Type 'Toggle between LAST level/OFF'

Short
after a short push on the button, the fan will switch between OFF and the last active speed of the fan. When the fan is running at medium speed, then with a short push the fan will go OFF. Again, a short push switches the fan to medium speed.
Long
operation is identical to 'Short'.

Type 'Toggle between: SET level/OFF:

  • Short: after a short push on the button, the fan will switch between OFF and a predefined speed.
  • Long: operation identical to 'Short'.

Type 'SET Level:

  • Short: The fan will be switched to the predefined level.
  • Long: operation identical to 'Short'.

Type 'Fan speed NEXT (circular):

  • Short: The fan will go to the next speed (OFF > LOW > MED > HIGH > MAX > OFF > …).
  • Long: operation identical to 'Short'.

Type ' Fan speed UP:

  • Short: The fan will go to a higher speed. (OFF > LOW > MED > HIGH > MAX)
  • Long: operation identical to 'Short'.

Type ' Fan speed DOWN:

  • Short: The fan will go to a lower speed. (MAX > HIGH > MED > LOW > OFF)
  • Long: operation identical to 'Short'.

Function behaviour when used in another function

Image169

  • SET level: this parameter defines the desired fan speed. The Parameter can be set from OFF to Max. The target speed is set to High by default. Following settings are possible:
speed X
when a function is activated the fan will go to the set speed (Off-Max).
speed X/Off
when a function is activated the fan will go to the set speed (Off-Max). When the function is switched off the fan goes off.
Not every function can be switched off. Consult for this matter the description of the respective function.
