Comparing Motorized Window Controllers

Within the last two weeks, I had noticed an increase in the number of customers who have called inquiring about wanting to install some type of motorized controller to open and close their skylights and windows.  The windows of concern are usually hopper or awning windows, and are typically mounted up high, making manual operation cumbersome at the least.  Just so you know, a hopper window is hinged at the bottom, whereas the awning window is hinged at the top. The skylight, of course, is mounted through the ceiling.  Regardless of window, you need to have a tall ladder or a telescoping pole crank to operate these units.

Home Controls does not sell ladders or pole cranks, but we do carry motorized chain actuators that can be used on skylights and on both types of windows.  Two of the more popular chain actuators are the Ultraflex Vega and the Sintesi.  Both units are powered by line voltage, and can be controlled either by a wall switch, or if automation is required,  a module with environmental sensor and contact closure inputs can be used.  RF control is an option, too.  The Vega is the recommended actuator of choice for most appliations.  Though its pull-in force is not as strong nor is its chain speed as fast as that of the Sintesi, here are some key benefits that the Vega has over the Sintesi:

• Lower electrical current draw.
• Self adjusting, electronic limit switches simplifies installation and requires less maintenance.
• The chain exits the center of the case for a balanced, aesthetic look.
• The Vega is supplied with pivoting mounting hardware.
• The Vega is readily available in stock through our supplier.

Take a look at the comparison chart between these two chain actuators, and note the stroke and force of each unit.  If your window falls within the capacity of the Vega, you will not be disappointed with its performance. If, however, you need that additional ooomph when pulling in a heavy hopper window, then the Sintesi will be the one to meet that task.

If you need additional information or have questions on either unit, you know how to get hold of me. I’ll be glad to share with you the installation and wiring diagrams.
