MT010-N, MT010-3MN
SMALL LINEAR THERMOELECTRIC ACTUATORS
Application
MT010-N and MT010-3MN Small Linear Thermoelectric
Actuators are used with Honeywell room-temperature
controllers for time-coupled modulating regulation of heating
and cooling systems. A microprocessor-based positioner
guarantees accurate control. The actuators are designed for
applications where space is limited.
Suitable valves include:
the 2-way and 3-way V58xxA/C series of small linear
valves with 2.5-mm stroke;
TRV's V300 and V2000;
Therafix TRV V2464 and V2474 series with 2.5-3-mm
stroke
Thermostatic radiator V90 valves with connection size
M30x1.5.

"First Open" Function
Fig. 6. "First open" function
A calibration process is carried out in order to optimally adjust
the actuator to the existing valve each time the operating
voltage is applied. During this process, the actuator completely opens and closes the valve, while prominent points are
simultaneously stored. The control signal is ignored during
this process. After the calibration process, the actuator is
ready for use and converts the applied control signal into a
proportional stroke.
Adaption Check
Fig. 7. Adaption check
After the calibration process (drive is stopped), and if no
control signal is applied, you can check whether the correct
valve adapter is mounted. The stroke cap must be slightly
elevated, and you should not see any of the white area.
Auto-Calibration
The closing point (drive is closed) is checked twice daily in the
active status (U
calibration process is repeated.

Hash (Disturbing Signals)
The actuator reacts only to a control signal > 0.5 V; this is in
order to ignore interference voltage and hum voltage.
