motorized window blinds

Please note, this page is for TMDC-12-25-11-25-RS Ultra-Low Standby Motors, please see other tubular motor instructions here.

The ultra-low standby motor is designed for long term battery operation, particularly for use with 'in window' solar installations. It has an industry leading standby current consumption of 0.03 mA or 30 uA (30 micro-amps). 1 uA is one millionth of an Amp. This is approximately 1,000 times less than what our regular motors use (about 20 to 30 mA) while 'listening' for a command.

It accomplishes this with special circuitry that has no unnecessary components such as sound transducers, etc. For this reason, the operation is slightly different from our standard radio motors in that we substitute a slight motor 'jog' instead of a beeping sound. You can follow the instructions for programming and pairing our regular radio motors re channel assignments, but you must look for the motor to jog instead of waiting for a sound.

We have replaced the sound cues with the motor jog cues in the instructions below

1. Preparing the RollerTrol™ motor:


Figure 1: Set Program

Each RollerTrol™ motor has a a small hole on the outside edge of the cap at the wired end of the tubular motor. At the bottom of the hole is a small switch for activating the 'programming' mode of the motor. On newer units, the switch is concealed under a rubber membrane and can be activated with a finger press (does not require a screwdriver insertion).

You can feel a pronounced click when this switch is activated, when inserting a small screwdriver or similar item into the hole. You do not need to apply much pressure for this to be activated.


Figure 2: Wiring

Connect the motor to your power supply, then follow the instructions below to complete the programming.

A standard DC motor normally reverses direction when the polarity is reversed, but these units have special circuity that requires you observe the correct polarity.

Connect the red wire to the positive (+) power supply terminal, white to negative.

If you are operating more than 1 motor from the same power supply, wire the motors in parallel: connect both positive leads together and both negative leads together.

Please note that you can control the direction of the motor by programming (see step 5 below), but it will not function if you connect the wires in reverse (they are reverse polarity protected, so you cannot damage the electronics if you accidently connect it in reverse).

2. Preparing the Multi-Channel Radio Remote Control:

Slide the cover off the bottom of the remote control. A slight downward pressure with your thumb while you slide it off the bottom of the remote is all that is required.

After removing this cover, you will see the battery compartment in the center of the exposed section. If the button battery is not installed, insert it now. Please pay attention to the battery polarity. The battery has a large plus + sign on one side (see diagram below) - this should be facing up, towards you.

There are 2 switches on either side of the battery holder. The left one is labeled 'confirm' and the right one is labeled 'limit'. Please familiarize yourself with the location of these switches.

Note that there is a small indicator in the left hand top corner of the digital channel display that indicates when the remote is transmitting a control signal.

3. Clearing the Motor Memory:

  • Hold the setting switch down. After about 2 or 3 seconds, you will see the motor jog slightly.
  • Continue to hold the switch down for a few more seconds, until you see it jog again.
  • After you see the second jog, the memory clearing procedure is complete and you can release the switch.

The operation is done at this point - the memory has been cleared. You can reset the memory as many times as you like.

4. Assigning The Individual Channels:

  • Press the channel button until you see channel 01 displayed on the remote.
  • Hold the setting switch on the motor down for about 2 or 3 seconds. When you see the motor jog slightly, release the setting button. The motor is now in programming mode and is waiting for its channel assignment.
  • To complete the channel assignment, press the 'confirm' button inside the remote (left side). You will see the motor jog almost immediately; release the button when you do. 
  • Please Note: You have about 60 seconds to press the confirm button, otherwise the setup procedure will 'time out', and you'll have to start over. 

At this point, the operation is complete - the motor is assigned to channel 1. You should be able to activate the motor normally when channel 1 is selected on the remote control.

5. Testing the Motor Direction:

You should be able to run the motor at this point - try the up/down/stop buttons. If the motor runs in the opposite direction to the one desired, you can reverse the motor direction:

  • hold down the 'limit' switch, then hold down the stop button also (both at the same time).
  • after a few seconds, you will see the motor jog
  • release both keys and test the motor again (it should run in the opposite direction). 

Please Note: If you accidentally hold down the Confirm button, instead of the Limit button: This puts it into the travel limit setting mode, and you have to complete the operation before you can go back to the reversal programming. You can tell if you're in that mode because the motor will 'jog' in small steps in one direction or the other, so that you can accurately set the travel limits. You have to complete both up and down travel limit settings before you can get out of that mode (see step 7).

6. Assigning Motor to 'ALL' Group:

As a convenience, each motor is automatically assigned to the ALL group when it is paired with another channel. There is no need to assign it separately.

You can create groupings of motors by assigning them to a different channel; motors cannot be excluded from the ALL channel.

7. Setting the Upper and Lower Travel Limits:

The travel limits of a RollerTrol™ motor can be set and changed at any time with the remote control; you do not have to touch the motor at all. The sequence is as follows:

Setting the Upper Limit:
  • Press and hold down the 'Limit' button (figure 4) for 3 seconds, until you see the motor jog. This action places the motor into its limit programming mode.
  • Press the UP button on the remote; the motor will move in the up direction at normal speed.
  • When it gets close to the upper limit, press the STOP button. The motor now enters the 'Jog Positioning' mode.
  • Press the UP or DOWN buttons to move the motor slightly in one direction or the other. You'll see the motor move in very short steps that are a small fraction of a full rotation. Use this mode to position your motor at the exact upper limit you desire.
  • Press the 'Confirm' button. After you see the motor jog slightly, the upper limit has been set. The motor is still in 'programming mode' so that you can set the lower limit (you cannot exit the programming mode until this is done).
Setting the Lower Limit:
  • Press the DOWN button on the remote; the motor will move in the down direction at normal speed.
  • When it gets close to the lower limit, press the STOP button. The motor now enters the 'Jog Positioning' mode.
  • Press the UP or DOWN buttons to move the motor slightly in one direction or the other. You'll see the motor move in very short steps that are a small fraction of a full rotation. Use this mode to position your motor at the exact lower limit you desire.
  • Press the 'Confirm' button. After you see the motor jog again, the upper limit has been set. The motor is now back in normal running mode and you should be able to test the full excursion.

8. Repeat the above steps for each motor:

The process is the same for all motors in the group, but each one will normally be assigned to a different channel (although you CAN assign multiple motors to the same channel). Once the travel limits have been set, they will be observed for each individual motor, even when activated simultaneously in Group Mode with the ALL button.

9. Using Multiple Remotes:

You can assign a motor to more than one remote control; the motors can 'learn' the bit pattern of more than one remote. Note that no two remotes use the same encoding, so you must go through the learning procedure with any additional remote you wish to use. The first remote assigned to the motor (after the initial clearing of memory) is considered to be the 'primary' remote and is the only unit that can be used to set the travel limits and motor reversal.

10. Extending Radio Motor Control: Use Any Web Enabled Device

With our zwave interface and the plug-in for Vera™, you can later extend control of your window blind radio motors to any browser on your web enabled devices (PC, phone, tablet, etc). VeraLite is the bargain of the year when it comes to full blown home automation systems - and the most user-friendly.

We sincerely hope you enjoy using these advanced motors; if you have any questions, please feel free to contact us at any time!
