1.3 INSTALLATION NOTES
The installation and, if necessary, the maintenance and the disassembling must be
carried out by a qualied electrical installer.
The installation must be compatible with local regulations.
Check the maximum circuit length for your circuit breaker in the next table:
Maximum circuit length at 230 VAC and for 5°C start-up temperature
C-characteristic circuit breaker
Multiple units on multiple power points can be used if longer heating cables are
required. We recommend to use nVent RAYCHEM SBS-FP-xx16A panels to operate 3,
6, 9 or 12 heating circuits

The nVent RAYCHEM Raystat V5 has a removable top lid. Both top and bottom of the box
have electronic parts and are connected to each other by an Ethernet connector cable.
The unit is delivered with top lid and back part dismantled.
Warning: For over voltage protection (e.g. in case of thunderstorm) we recommend
the use of an external over voltage protection device.
Care and maintenance
Clean the Raystat V5 with a soft damp cloth only, do not use any solvents. Do not
pour water directly on the device. Do not use a water hose or a high pressure cleaner.
Avoid installing the controller in rooms with high humidity and condensation. To
operate the user interface, it must be clean and dry. For outdoor installation it will be
recommended to use a sun & rain cover.
Description
nVent RAYCHEM Raystat V5 is an electronic control thermostat with display,
advanced alarm facilities and the capability of switching large currents (25 A). The
Raystat V5 is designed to control nVent heating cable systems. Heating cable can be
controlled (switched ON/OFF) either directly by the Raystat V5 or via a contactor.
Direct switching of heating cables is possible for heating loads up to 25 A.
For heating loads above 25 A indirect switching via a suitably rated contactor con-
trolled by a Raystat V5 is necessary.
Installation and all wiring must be in accordance with applicable regulations.
The device must be installed in non hazardous areas only. nVent offers other controls
for use in hazardous areas.
The sensor must be installed. Attention: The sensor position on pipe or in Air
needs to match the operation mode PiPE or Air. (PASC / ambient temperature
measurement control). A wrong assignment can led to a frozen pipe.
An alarm terminal makes remote signalling of errors possible. During commissioning
of the unit it is recommend to simulate sensor functionality in PIPE sensing mode,
since the AIR/PASC mode is not suitable for this test due to delay in the PASC algo-
rithm. The unit can be pre-programmed in power-off mode by external power bank (to
be ordered separately) connected via A-A-USB cable and USB connection.

Sensor installation for higher temperature ranges:
For higher temperature ranges up to 250°C a PT100 type of sensor can be connected
by using the sensor-Plug-In Module SM-PT-100-1 (PCN: 1244-022441). A reset of
the unit is needed to recognize this new hardware module and to activate the new
temperature range.

OPERATION
The Raystat V5 has a LED user screen interface: The unit will switch to the main
screen after 2 minutes of non-interaction on the parameter input screens.
Quick install
When the unit is powered up for the rst time, a quick setup must be executed before
the unit is ready to start. The Quick start helps to set all important settings, the
unit will go in main screen mode automatically when done. Quick start is sufcient
for normal operations. More settings are available in the Setup menu for special
installation conditions.
The Quick start will only start if no pre-setting is done.
