TTC-2000 is a 3-phase triac controller for controlling electric heating up to 25 A. It is made for wall mounting. TTC-2000 is to be connected in series between power supply and an electric heater and can control both Y- and Delta- connected loads. TTC-2000 can control assymetrical Delta-loads.
Function
The controller pulses the entire power output ON/OFF and utilises time-proportional control, the ratio between On-time and Off-time is varied to fit the prevailing heating requirement. E.g. ON = 30 sec and OFF= 30 sec gives 50% output power. The cycle-time (the sum of on-time and off-time) is adjustable 6...120 sec.
TTC-2000 automatically adapts control mode to suit the dynamics of the controlled object.
Supply air temperature control
For rapid temperature changes, TTC-2000 will work as a PI-controller with a fixed proportional band of 20K and a fixed reset time of 6 minutes.
Room temperature control
For slow temperature changes, TTC-2000 will work as a P-controller with a fixed proportional band of 1.5 K. When running room temperature control the supply air temperature can be maximum and/or minimum limited.
Controlling larger electric heaters
At larger loads TTC-2000 can be combined with ancillary board TT-S1
