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
- 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.
