Technical data

Description

The STZ-180 RS n actuator is used to control three-way and four-way mixing valves. It is controlled by a 3-point signal. The actuator has a manual control option accessed with use of a pull-out knob. It is also equipped with a display and a valve temperature sensor. The rotation range of the actuator is 900 and the rotation time is 180s.

The STZ-180 RS n actuator is supplied with an adapter that allows for its easy installation on the rotary mixing valve.

Operating

When the actuator is started, the programme number is displayed for 10 seconds. After this time, the displayed values for the set and current temperature and the percentage of valve opening change every 5 seconds. When calibrating the valve, instead of the percentage value of the valve opening, CAL will be displayed.
Use the MENU button to enter the menu function. Switching parameters of the menu functions is done using the PLUS and MINUS buttons. To edit the selected parameter, use the MENU button.
MENU functions:
ON/OFF – current valve status: ON or OFF
t. CH/t. FL – valve type: CH or Floor (FL)
d.L/d.r – change valve opening direction
FAC – restore the factory settings (hold the MENU button for approx. 3 secs.)
Pr – manual operation functions
E.- – exit from the menu
The auxiliary switch (set to any position) is available as pre-installed equipment or as optional equipment. After removing the knob under which the cam is located, adjusting the auxiliary switch is easy and does not require disassembly or the use of any tools.
