VARIHEAT AA SYSTEM OWNER INSTALLATION MANUAL
“Remote Damper” control – terminals 63/64/65
For control of a remote damper when Advanced Frost Protection is active.
These are powered terminals. Terminal 63 is Live (230V) when Advanced Frost
Protection is active. Terminal 63 is fused at 160mA at 230V. TerminaI 64 is
Neutral. Terminal 65 is Earth.
If this facility is not required, these terminals do not need to be used.
Advanced Frost Protection
(Used when the remote damper is installed).
Advanced Frost Protection behaves in the same way as the standard Frost
Protection with the addition of closing the remote damper. It also activates
under the same conditions as standard, but will not deactivate when the
temperature rises immediately. Instead, the machine will check the ambient
temperature periodically (every six hours by default).
For each check, the remote dampers are opened for a short time (five minutes),
fresh air is allowed to reach the probe and if the temperature has risen above
the set point then Advanced Frost Protection is deactivated. If the temperature
is still too cold, the machine remains in Advanced Frost Protection mode until
the next check. An option to force a check can be found on the Set Points and
Switches screen in the User Settings but only while Frost Protection is active.
3.7 NETWORK CONNECTION
Local area network connection
For screen mirroring to function (see Section 2.2 Remote access) the Variheat
touchscreen must be connected to a LAN (local area network). The RJ45
Ethernet port on the back of the touchscreen should be used. The Ethernet
controller supports the MDI/MDIX auto-crossover cable function, and may be
used with either T568A or T568B wiring standards.
The default network IP address for the Variheat is 192.168.1.150, but may be
changed as required (see section 2.1 Network setting).
If the Variheat is only to be accessed by devices connected to the same
network, no further network setup is necessary. If the Variheat is to be accessed
from devices NOT connected to the same network, it is necessary to set port
forwarding to the network IP address of the Variheat.
Ports to be forwarded

If the Variheat is to be accessed from devices NOT connected to the same
network, a static public IP address for the network is recommended. If your ISP
(internet service provider) is not able to provide a static IP address, third party
solutions are available to provide a static IP address, which may involve a cost.
Once set up, the Variheat may be accessed from an ActiveX enabled browser
such as Internet Explorer, or a mobile device using the Vijeo Design’Air app. See
section 2.2 Remote access for more details.
