18 Accessories
18.1 Sensors and measuring instruments
Temperature sensors
The product range includes high-precision platinum temperature sensors, fl atscrew
sensors, outdoor temperature sensors, indoor temperature sensors, cylindrical
clip-on sensors, also as complete sensors with immersion sleeve.
Overvoltage protection device
In order to avoid overvoltage damage at collector sensors (e.g. caused by local
lightning storms), we recommend installing the overvoltage protection SP10.
V40 fl owmeter
The V40 is a measuring instrument for detecting the fl ow of water or water/glycol
mixtures. After a specifi c volume has passed, the V40 reed switch sends an impulse
to the calorimeter. The heat quantity used is calculated by the calorimeter using
these impulses and the measured temperature difference with the help of pre-de-
fi ned parameters (glycol type, concentration, heat capacity, etc.).
18.2 VBus

accessories
Smart Display SD3 / Large Display GA3
The RESOL Smart Display is designed for simple connection to RESOL controllers
with RESOL VBus
®
. It is used for visualising data issued by the controller: collector
temperature, store temperature and energy yield of the solar thermal system. The
use of high-effi ciency LEDs and fi lter glass assures a high optical brilliance. An addi-
tional power supply is not required. One module is required per controller.
The RESOL GA3 is a completely mounted large display module for visualisation of
collector- and store temperatures as well as the heat quantity yield of the solar sys-
tem via one 6-digit and two 4-digit 7-segment-displays. An easy connection to all con-
trollers with a VBus
®
is possible. The front plate is made of antirefl ective fi lterglass and
is printed with a light-resistant UV-lacquering. The universal VBus
®
allows the parallel
connection of 8 large displays as well as additional VBus
®
modules.
AM1 Alarm module
The AM1 Alarm Module is designed to signal system failures. It is to be connected
to the VBus
®
of the controller and issues an optical signal via the red LED if a failure
has occurred. The AM1 also has a relay output, which can e. g. be connected to a
building management system (BMS). Thus, a collective error message can be issued
in the case of a system failure.
