Differential temperature control 2 sensor operation

The ATR-3 electronic clock thermostat gradually controls the speed of
REMKO DVL ceiling fans between 1 and a maximum of 14 and controls
a warm air heater.

The unit works with two sensors: a room temperature sensor at operat­ing height and a ceiling temperature sensor. Unused warm air that rises
to the ceiling in high rooms is measured by the ceiling temperature sen­sor.

If the room temperature falls below the set target temperature
(adjustment knobs A und B) and, at the same time, the ceiling tempera­ture is above the room temperature by a set differential value
(adjustment knob C), the REMKO DVL ceiling fans start running and
transport the warm air down. The warm energy from the ceiling area is
can be used again in the work area.

If the difference in temperature increases, the fan speed also increases
up to the maximum speed. The minimum and maximum fan speeds are
adjustable (adjustment knobs F and G). The fan performance is dis­played by indicators (M) on the display of the weekly clock timer (K).

If the room temperature falls by a specific, adjustable value (adjustable
knob E) below the target value, the heat also switches on. The operating
mode is displayed by a LED (N)

A digital weekly clock timer with power reserve makes it possible to pro­gram heating and cooling off periods.

Proportional control 1 sensor operation

To meet special requirements, the unit can also be used for pure propor­tional control. In this case, the “Heating” and “Cooling” operating modes
may be selected.

In the 1 sensor mode, only the room temperature is measured. If the tar­get value of the room temperature goes above or falls below the value
set on the control mechanism Xp (D), the ceiling fans start running.

If, during “Heating” mode, the room temperature falls by a specific, ad­justable value below the target temperature, the heat also switches on.

If the heating relay is not regulated during “Cooling” mode, the air is only
circulated.

In the "Setting the Functions" menu, the operator can switch from dif­ferential temperature control to proportional control and from heating to
cooling is performed (see page 9).

The second sensor does not have a function. It can be used as a place
to perform measurements (display for 3 seconds after pressing the SET
program button).

LCD Display of the Clock Timer

The timer, day of the week and current tempera­ture of the temperature sensor are shown on the
LCD display. By pressing the SET program but­ton, the temperature of the 2nd temperature sen­sor can be displayed for approx. 3 seconds.

Day and Night Temperature

The target values for day and night temperature can be set independently of
one another and are standard for the control depending on the operating
mode (day or night operation). The minimum target values can be limited to
5°C by an internal setting.

Frost Protection Temperature

The frost protection temperature is fixed at 5 °C. By pressing the two pro­gram buttons + and – at the same time, the frost protection temperature can
be selected.

Hand Button

The > button makes it possible to change the current temperature opera­tion (comfort temperature / cooling temperature) in automatic mode. The se-

lected temperature mode is displayed by indicators on the right-hand side of
the display. This function is deleted the next time the program is opened.

Off

By pressing the two program buttons ¹ and + at the same time, the control
is switched off. The operating mode is no longer displayed on the right-hand
side of the display. The unit continues to record the current temperature but
all control functions are completely switched off.

Reset

There are two different reset options:

1. Start up reset:
The RESET button makes impossible to restart the unit after operation has

been to interrupted due to a malfunction. The clock must be reset but the
program and parameter settings are retained.

2. Global reset:
To force the unit to restart with the factory settings, the buttons RESET, +

and – must be pressed at the same time. After the RESET button is re­leased, the buttons + and – must be held down until the version number
(r 10...) appears on the display. The clock must be reset, Any previously en­tered individual timer program and any parameter settings are lost.
