The Temperature Difference Controller AIR TDC facilitates ef cient use and function
control of your solar or heating system. The device is impressive most of all for its
functionality and simple, almost self-explanatory operation. For each step in the input
process the individual entry keys are assigned to appropriate functions and explained.
The controller menu contains headwords for the measured values and settings, as well
as help texts or clearly-structured graphics.
The AIR TDC can be used as a temperature difference controller for the various sys-
tem variants illustrated and explained under B.5.
Important characteristics of the AIR TDC:
• Depiction of graphics and texts in a lighted display
• Simple viewing of the current measurement values
• Analysis and monitoring of the system by means of statistical graphics,etc.
• Extensive setting menus with explanations
• Menu block can be activated to prevent unintentional setting changes
• Resetting to factory settings
• A wide range of additional functions are available.

Caution
The following illustrations should be viewed only as schematic diagrams
showing the respective hydraulic systems, and do not claim to be complete.
The controller does not replace safety devices under any circumstances.
Depending on the speci c application, additional system components and
safety components may be mandatory, such as check valves, non-return
valves, safety temperature limiters, scalding protectors, etc., and must
therefore be provided.

Caution
C.1. Wallinstallation
Install the controller only in dry areas and under the ambient conditions de-
scribed under B.1 “Speci cations”. Carry out the following steps 1-8.
1. Unscrew cover screw completely
2. Carefully pull upper part of housing
from lower part.
3. Set upper part of housing aside, being
sure not to touch the electronics when
doing so.
4. Hold the lower part of the housing up
to the selected position and mark the 3
mounting holes. Make sure that the wall
surface is as even as possible so that the
housing does not become distorted when
it is screwed on.
5. Using a drill and size 6 bit, drill 3 holes
at the points marked on the wall and push
in the plugs.
6. Insert the upper screw and screw it in
slightly.
7. Fit the upper part of the housing and
insert the other two screws.
8. Align the housing and tighten the three
screws.

Installation
C.2. Electrical connection
Danger
Before working on the unit, switch off the power supply and secure it
against being switched on again! Check for the absence of power!
Electrical connections may only be made by a specialist and in compli-
ance with the applicable regulations.
Do not use the controller if the housing shows visible damage.
Caution
Low-voltage cables such as temperature sensor cables must be routed
separately from mains voltage cables. Feed temperature sensor cables
only into the left-hand side of the unit, and mains voltage cables only
into the right-hand side.
Caution
The customer must provide an all-pole disconnecting device, e.g. a
heating emergency switch.
Caution
The cables being connected to the unit must not be stripped by more
than 55mm, and the cable jacket must reach into the housing just to the
other side of the strain relief.
With hydraulic variant D1 - D8 relays R1 and R2 are switched on
simultaneously to allow the connection of another load at R2.
If in D1 speed control is active, R2 is switched on during purging time.
Caution

1.Select necessary program/hydraulics
(Fig. B5)
2.Open controller as described under C.1.
3.Strip cables by 55 mm max., insert, t
the strain relief devices, strip the last
8 - 9mm of the wires (Fig. C.2.1)
4.Open the terminals using a suitable
screwdriver (Fig. C.2.1) and make electri-
cal connections on the controller (s. D.1
- D.20)
5.Re t upper part of housing and fasten
with screw.
6.Switch on mains voltage and place con-
troller in operation.
C.2.1
Installation
C.3. Installing the temperature sensors
The temperature sensor cables must be routed separately from mains voltage
cables, and must not, for example, be routed in the same cable duct!
The controller operates with Pt1000 temperature sensors which are accurate to the
degree, thus ensuring optimal control of system functions.
If desired the sensor cables can be extended to a maximum of 30 m using
a cable with a cross-section of at least 0.75 mm². Make sure that there is no
contact resistance!
Position the sensor precisely in the area to be measured!
Only use immersion, pipe-mounted or at-mounted sensor suitable for the spe-
ci c area of application with the appropriate permissible temperature range.
