    Hello.
    A colleague of mine has a backyard workshop with a glass roof over which there is an awning. Inside, the temperature rises considerably on hot days. The awning is controlled manually. The plan is to install a control that depends on the interior temperature. When the temperature rises, the awning will automatically close. When the temperature drops to a certain level, the controller will open the awning to heat the room. It is important to keep the temperature constant as a sports car parked inside is not well affected by major temperature fluctuations. Is there a ready-to-use controller that would enable such a control? If not, how can such an installation be made? The awning is powered by a standard 230V motor.
    Regards

    A simple temperature controller with a relay which gives a close signal when a certain temperature is exceeded. Usually the probe is on a cable, but it can also be attached to a piece of black metal sheet so that the temperature reading is higher in bright sunlight.

    Thank you for your reply. I was also thinking about such a controller. Only they work on the on/off principle and here you need a second signal to open the blind when the temperature drops. In addition, the problem is that the signal given for closing or opening cannot be constant, when the awning is fully open it cannot be live all the time (so it seems to me in theory). It would be better if the signal was cut off when the motor was fully running.

    As a driver you can use:

    Two independent settings; e.g. above the top - extends the awning, below the bottom - retracts.
    There must be limit switches at the motor or on the awning track to cut off power to the motor at extreme positions.

    I think that actually such a double steerer will be the best solution. Thank you very much for your answers.
    Regards.

    Alternatively arudino mini or nano and with relay output module . A low-cost solution, but you need to know how to program. Then you can add the cardinal times of the outputs in the program. You will not be able to avoid limiters, though.

    They do not cut off the power to the motor just give info to the controller "stop open" "stop close".

    Not necessarily - as the motor is relatively low power - you can treat the external limiters in the circuit like the built-in limiters in some roller shutter motors. Also, there is no need to expand and separate into a "power" system and a "control" system as would be the case with, say, a 3-phase or 1-phase motor of greater power.

    Thank you for your replies. As I live abroad I have been looking for similar equipment here so that there are no shipping issues. Here is a link to the equipment I wanted to ask if it would be suitable (price wise it looks good and that's what worries me):

    https://www.ebay.de/itm/10A-220V-Digitaler-Te...057987?hash=item2abe766a83:g:AUIAAOSwVRBcEhG6

    Another thing is that the motor is a typical motor for operating roller shutters. It has a built in tap, so if I understand the unit will stop in the same way as it stops with manual operation, if I hold the button down and the awning is fully open, the tap will cut the voltage on the motor, and it won't have any effect on them staying live all the time?

    I'm not sure if the unit above has relays built in. If not I understand that you would need to add relays between the controller and the awning.
    Well and most importantly, the motor is controlled clockwise, counterclockwise i.e. typically you change the plus minus to have the correct direction of rotation. These controllers are to operate separate units as I understand it. Will connecting one motor to both outputs not interfere? I have one minus wire and two plus wires to control right or left.
    These may be simple questions but I'm not familiar with this in theory, and I'm relying on a vascular explanation.

    They can't cut the power supply to the motors, because how will they work the other way without voltage? Switch the windings for the directions of operation then yes. But that's something the controller has to know about.... :)

    For a DC motor (two wires connected to "+" and "-"; and then to reverse polarity - to get movement in the other direction), there is also a solution: rectifier diodes are inserted in parallel to the limiters.
    Here, judging from the description

    we have a simpler solution: a double-winding motor with a capacitor (depending on which side of the capacitor you give power to it spins in a particular direction.

Topic summary

A user seeks to automate an awning control system based on interior temperature for a workshop with a glass roof. The goal is to close the awning when temperatures rise and open it when they drop, ensuring stable conditions for a sports car stored inside. Suggestions include using a temperature controller with relay outputs, such as the DUET BIS model, which allows for independent settings for extending and retracting the awning. Alternatives like Arduino-based solutions were also proposed, requiring programming knowledge. The discussion emphasizes the need for limit switches to prevent motor damage and the importance of understanding motor control principles, particularly for reversing motor direction. The user is exploring available equipment options and compatibility with their existing motor setup.
