Control Options

Three types of controller are available: Basic, Plus or Automatic. The control panel

allows you to control the climate separation between the inside and outside air, in a

simple and comfortable way.

1. Basic Controller (RTRD)

The five-speed switch allows you to match the volume of air to different conditions.

The RTRD controller has a rotary control switch for five speeds, a neon indicator and

an input for a door contact switch or thermostat.

2. Plus Controller (RDP)

The Plus controller has two five-speed switches:

Position 1: with open door

The rotary speed switch is set to the desired operating position for when the doorway

is in use - door open.This speed/or setting is activated by a door switch wired to the

controller.

Position 2: with door closed

When the door is closed,the unit returns to a lower speed setting, again selected with

the rotary speed switch, and adjusted to the desired operating position. This setting

is generally lower than the position 1 setting so that the air curtains act as a back-

ground heating device. A room mounted thermostat is connected to the controller to

switch off the units when the desired indoor temperature is achieved.

3. Automatic Controller

In situations where doors must be open frequently and for longer periods of time,it is

difficult to ensure a constant indoor temperature as the external conditions can change

continuously throughout the day. The automatic controller is developed to economically

create a comfortable indoor climate in these changing situations.

The controller operates by controlling both the water/or electric heating capacity and

the fan speed to provide an automatically adjusted air flow and heat output,matched

to the particular climate requirements.This controller ensures that only the heat energy

required is used.

The controller has an automatic five speed operation, plus sensor inputs from:

• Integrated floor sensor

• Internal temperature sensor

• External temperature sensor

The control panel has the following

dimensions: 600 x 330 x 205 mm (l x w x d).

Basic controller (RTRD) with neon indicator.
