OPTI-TEMP (G433) is a
n
optional device of OPTI-ENER system that enables to manage energy surpluses for heating purpose. In most cases the controller is
used to heat-up a domestic and heating water or air – by any resistance heating elements.
a
Controller has been equipped with
variable voltage regulator
to supply resistance heating element e.g. electric heater. Power of electric heater will be
adjusted to actual energy surpluses measured constantly. To provide proper work of the device it is required to set up a ,,Supply power” correctly at
electric heater regulation at opti-ener.com. OPTI-TEMP is able to control electric heater up to 2000 W. OPTI-TEMP has two addition potential free
contacts with following parameters – 230V AC and maxiumum load 16 A
.
Temperature measure
allows to turn on/off heating element after exceeding desired values. NTC temperature sensor (10 kOhm) is a part of OPTI-TEMP set. In
case of extraordinary measure conditions to unblock setting range please put 20-30 kOhm resistor to temperature sensor input.
It is possible to install 3 addition temperature sensor although they do not take a part in control.
Potential free contacts can be turned on manually for 60 seconds by pushing manual switch on the cover of OPTI-TEMP. Thanks to OPTI-ENER user is also able to
control supply power automatically according to energy surpluses or time schedule. Settings are available at website opti-ener.com
CAUTION:
If your OPTI-ENER system contains two optional modules Converter PV and OPTI-TEMP than please make sure to connect the OPTI-TEMP
module first.
Connection steps
:
Connect the power cable to OPTI-TEMP.
Connect communication wires to port RS485 in OPTI-TEMP module and port RS485-2 in OPTI-ENER module or Radio G931.
Push the B2 button at the top of the OPTI-ENER cover (diode LED2 should blink).

If the connection will be successful than signal diodes at OPTI-TEMP will start pulsing. In addition at opti-ener.com at Scheme and also at Settings menu in
Parameter Settings card new control settings should appear. In case of connection failure please reset the OPTI-ENER module by pushing and hold B2 button
until LED1; LED2 diodes will turn on and repeat steps I-III.
CAUTION: In order to restore fabric settings please make a short-circuit of 3-rd and 4-th (up) pins mounted at OPTI-TEMP printed circuit board. Pins are located
in distance of 1,5 cm (0,6 inch) on the right side of manual switch 2.
