TLC3-ECO Economizer
Features
Compares outdoor temperature with indoor or control
temperature. Activates free heating or cooling.
Low power energy consumption: < 1W per unit
Relays switching for outputs each up to 300W
Optional external temperature control input
Choose between one 3-point actuator and 2 binary
outputs. (1 outdoor damper, 1 mechanical enable or fan.)
Password protected programmable user and control
parameters
TLC3-ECO-D also includes
Power cap protected real-time clock with 48hr power
backup
Time schedule events, with many options
Blue backlight
Infrared remote control receiver
Applications
Economizer:
Control of outdoor
damper
For 3-point or spring
return actuators
With enable for
mechanical heating
or cooling or fan
General
TLC3-ECO: 1 independent temperature control loop with 1 heating and 1 cooling sequence. 1 internal
temperature sensor, 1 outside temperature input, 1 auxiliary input for external temperature input, heat –
cool changeover or high/low limit.
The economizer controls an outdoor damper and optional fan. It activates the outdoor damper if there is
heating or cooling demand and if outdoor conditions are favorable for free heating or cooling. An additional
input may be used to close the damper based on an open contact input (for example high humidity or bad air
quality).
Flexible application configuration is made with a parameter-setting routine using the standard operation
terminal.

Temperature sensors
: Use Vector Controls NTC sensors to achieve maximum accuracy: SDB-Tn10-20 (duct),
SRA-Tn10 (room), SDB-Tn10-20 and AMI-S10 as immersion sensor.
Binary auxiliary device
s (e.g. pumps, fans, on/off valves, etc): Do not directly connect devices that exceed specified
limits in technical specifications – observe startup current on inductive loads.
