INSTRUCTIONS
Triac controller for proportional control
of electric heating
TTC2000 is a proportional controller for electric heating with automatic
voltage adaption. TTC2000 pulses the whole load On - Off. The ratio
between On-time and Off-time is varied 0 - 100% to suit the prevailing heat
demand. The current is always switched at zero phase angle to prevent
RFI.
TTC2000 is primarily intended for use with Regin TG-sensors for either
supply air control or room control with maximum and/or minimum limiting of
the supply air temperature.
TTC2000 can also be controlled by an external 0...10 V DC control signal.
TTC2000 can control both symmetrical Y-connected 3-phase heaters and
symmetrical or asymmetrical Delta-connected heaters.
TTC2000 is only intended for electric heating control. The control principle
makes it unsuitable for motor- or lighting control.
Installation
Mount TTC2000 on a wall or in a cabinet or other enclosure.
Mount TTC2000 vertically with the text right side up.
Protection class: IP30.
Ambient temperature: 0 - 40°C
N.B. TTC2000 emits approx. 45W of heat at full output which must be
dissipated.
N.B. The front cover has no hinges and can fall out when the screw is
unscrewed.
Wiring
Supply voltage (fig 1)
Terminals L1in, L2in and L3in.
Supply voltage: 210-255 or 380-415V AC
3 phase, 50 - 60 Hz with automatic voltage adaption.
Maximum current 25A/phase.
N.B. The supply voltage to TTC2000 should be wired via an all-pole switch
with a minimum contact gap of 3mm.
N.B. TTC2000 must be earthed.
Load (fig 1)
Terminals L1out, L2out and L3out.
Resistive 3-phase heater without neutral.
Maximum load: 3300W/phase at 230V phase - phase voltage (25A).
5750W/phase at 400V phase - phase voltage (25A).
Minimum load: 530W/phase at 230V phase - phase voltage (4A).
920W/phase at 400V phase - phase voltage (4A).
The terminal block is of screwless type.
In order to open the clamping jaws, press a screwdriver into the upper,
rectangular slot. See fig 2. Insert the wire into the larger round hole and
remove the screwdriver. Check that the wire is securely clamped.
INSTRUCTIONS
Main sensor and external setpoint (figs 3-7)
Terminals 1 and 4. Low voltage. Not polarity sensitive.
N.B. Terminals 2 and 3 are internally connected and are used
to simplify wiring when using external setpoint.
N.B. Choice of internal or external setpoint is made using
switch 1.
Limiting sensor (fig 8)
Terminals 5 and 6. Low voltage. Not polarity sensitive.
When running room temperature control the supply air temperature can
be limited to a maximum and/or a minimum. The limiting sensor is placed
in the supply air duct after the heater.
Choice of function is made using switches 2 and 3. Choice of limiting
temperatures is made on potentiometers Min and Max.
N.B. As limiting sensor TG-K360 must be used.
