Installation:

Roll up motors to incremental controller (thermostat model)

1) Install the telescopic tubes. The arm is installed on the gable wall baseboard, typically 1.5 meters from the roll up tube. Check the tube extension to ensure that there is sufficient length to reach the top of the roll up wall. Lubricate (not supplied) the tube.

The smaller diameter tube is attached to the baseboard.

2) Connect the telescopic pivot tube to the motor.

3) Attach the output coupler to the motor and bolt them - attach the roll up tube to the output coupler, but do not bolt them together until the limit switches are adjusted (see the hint below).

4) Wire the motors to the box (the motor outputs are in pairs on the box). Make temporary connections until you are sure the motor is winding in the correct direction. Position the box to avoid excessive lengths of power cable (from the box to the motors) to minimize voltage drop to the motors.

.

warning, when only a single motor is attached to the box ensure that with the unused motor output, the black wire is isolated from the white (to prevent a short and a blown fuse).

5) SETTING THE LIMIT SWITCHES

With the roll up wall at grade set the limit switch (each increment is a rotation of the motor), remove the cap, with a Phillips screw driver, push the dial in and then turn.

Setting the green dial at 1 and the red at 24 will move the wall up (and down) 23 revolutions. The dial closest to grade determines the lower stop.

6) Connect the thermostat to the box. The thermostat should be wired to make contact on a temperature rise. For the supplied thermostats connect black (from box) to black; and white (from box) to blue. As a general rule with the wall down have the thermostat set to its maximum range. Locate the thermostat away from the wall and away from any fans to avoid rapid temperature fluctuations.

7) For the incremental control boxes operated with a thermostat set the timer switches inside the box. The boxes are pre-set at 15 minute of off-time, and 15 seconds of on-time; these settings can be adjusted.

8) Heat wrap all electrical connections.

Motor Warranty:

We will provide a (reconditioned) replacement motor for any motors that fail within 18 months of purchase provided:

- they are installed with an Steele GC Inc.controller

- the motors do not sit in standing water;

- the limit switch caps are closed,

- the wall is covered with single poly only,

- the motor is installed in the manner specified above,

- the equipment is not modified.

There are 2 sets of white and blue dials, on a relay, inside the control box.

The top set controls the on time (t on) for the motors, the bottom set controls the off time (t off).

Each white dial has the following increments:

.1 - 1 second

1 - 10 seconds

6 - 60 seconds

1 - 10 minutes

6 - 60 minutes

1 - 10 hours

10 - 100 hours

This is the coarse adjustment.

The blue dial runs from 1 to 10 and is the fine adjustment, it selects the percentage of the coarse adjustment time period, that the motors will run.

For a run time of 15 seconds (this is the factory setting), set the white dial at 6 - 60 seconds, and the blue dial at 2.5 (25% X 60 seconds = 15 seconds).

For a run time of 30 seconds, set the white dial at 6 - 60 seconds and the blue dial at 5.0 (50% X 60 seconds = 30 seconds).

Roughly speaking it takes 15 seconds to roll up 6” of wall. Fifteen minutes later (off - time), the motor will energize again; if the temperature remains above the thermostat set point, the wall goes up; if the temperature has dropped the wall goes down. We suggest that these settings will provide a relatively stable temperature regime. Various greenhouses and conditions may require either more or less aggressive venting strategies.
