The RF-OPTIMA thermostat and the receiver have a binary code with which the channel can be set. The receiver has a button to link it with the
thermostat, which in turn has a button to link it. This linking has usually already been activated. Should this not be the case, the following steps
can be taken.
-Press the button on the receiver A); the green LED light will flash B). Turn off the thermostat!
-Press and hold the SET E) button on the thermostat for 3 seconds, the location channel) will be shown on the display in the
left corner of the thermostat. Press again on the SET E) button of the thermostat. You will hear a buzzing sound D) and
the LED lights on the receiver will stop blinking.
-The thermostat and the receiver are now linked. Press the SET E) button to continue.
The jumper E) can be removed to switch off buzzer mode.
The measured temperature of the RF-OPTIMA is easy to calibrate. Only use this function if the measured temperature deviates this happens if
you place the thermostat in a drawer or similar).
-Press and hold the SET E) button, in off mode, on the thermostat for 3 seconds; the code 8cAS or similar) will be shown in
the top left corner.
-Use the F) and – G) buttons to set the temperature value. This value can be adjusted by -8 to +8°C.
-Press the SET E) button on the thermostat to save this function and leave the menu.

-Press the SET button E). The frost protection (04) can be set between 0 ~ 5’C. When the
display shown --, then the frost protection is disabled.
-Change this values using the F) and – G) buttons.
-Press the SET button E). The high temperature set point level (05) is shown in display. With this
value you be able to maximize the high temperature set point level e.g. 45’C.
-Change this values using the F) and – G) buttons.
-Press the SET button E). The low temperature set point level (06) is shown in display. With this
value you be able to maximize the low temperature set point level e.g. 15’C.
-Change this values using the F) and – G) buttons.
-example low temperature is 15’C, high temperature is 45’C. The temperature can only be set
between these values).
-Press the SET button E). The software version (7) is shown in the display.
-Press the SET button E), save the settings and leave the menu.

The RF-OPTIMA provides the option to program 10 time and temperature settings, irrespective of the day, i.e. a total of 70 switching
programmes per week.
These are shown in the top day), centre time and temperature) and the bottom event) of the display.
Carry out the following steps to select the program you want:
-Press and hold the PRG button D) for around 3 seconds to enter the Programming settings, the series of figures at the top
and bottom of the display flashes; the day is shown in the top left starting with 1 as Monday), startup time and temperature
in the centre A and B) and program event in the right bottom corner.
-Change these values using the F) and – G) buttons. Use the PRG D) button and the F) and – G) buttons to set the
desired values.
-When entered the program setting see above) the time A) flashes, change the value with the F) and – G) buttons.
Each step is 15minutes.
-Press the PRG D) button, the temperature flashes B), change the value with the F) and – G) buttons. The temperature
can be set with steps of 0,5’C.
-Press the PRG D) button, the PRG program / event) flashes C). You be able to setup the next event.
The thermostat uses the setting from event PRG 0 till PRG 1. The setting from PRG 1 goes till event PRG 2, from PRG 2 till PRG 3, from PRG 3 till
PRG 4, from PRG 4 till PRG 5, from PRG 5 till PRG 6, from PRG 6 till PRG 7, from PRG 7 till PRG 8 and from PRG 8 till PRG 9. These are the 10
events per day.
The desired program function for the RF-OPTIMA is easy to set.
Press the PRG D) button to set the desired function program: PRG or manual: MAN)
-When the thermostat has the function PRG Program) the thermostat act like the pre installed programs see programming).
-When the thermostat has the manual function MAN), the thermostat act by the desired temperature used by the + and –
buttons. The thermostat doesn’t goes automatically to the program function!

The receiver can be mounted directly on a wall or in a flush-mounted box. Remove the fascia panel first of all; there are two indentations on the
bottom side which can be pushed in using a screwdriver.
The receiver has a connecting terminal which has 5 connections.
-Batteries should be replaced once a year to ensure accurate operation use alkaline AA batteries, 1.5 V, e.g. from Duracell).
-Treat the RF-OPTIMA thermostat and the receiver with care; the thermostat and the receiver have sensitive electronics.
-The RF-OPTIMA cannot tolerate moisture and extreme heat; ensure that the thermostat and the receiver are suitably protected.
