In automatic operating modes, the temperature setpoints can be individually adjusted
for every comfort period and for the continuous operating modes. The temperature
setpoint of economy mode is the same in automatic and continuous operation.
In frost or overtemperature protection mode, the room temperature is constantly monitored. If it falls (rises) below (above) the adjusted setpoint, control to the adjusted frost
or overtemperature protection setpoint
will be ensured.
The controller generates the 24-hour operating mode from its current 24-hour program.
It automatically selects the switch-on time of the first heating / cooling period and the
switch-off time of the last heating / cooling period to generate and display a complete
heating / cooling period. The comfort setpoint used by the controller is the currently
stored standard setpoint of continuous operating mode
. The self-generated 24-hour
operating mode is maintained until another operating mode is selected.

The switching program can be used as a 7-day or 24-hour program, depending on
programming. It is also possible to select one of the continuous operating modes
with which the switching program is not used.
With the 7-day program, all individual days, working days (1-5), weekend (6-7), or the
entire week (1-7) can be programmed.
For each heating / cooling period, 3 different switching patterns are available.
There is a choice of 1, 2 or 3 heating / cooling periods. For each heating / cooling period, the start time, end time and comfort setpoint are to be entered.
In between heating / cooling periods, it is always the same economy temperature setpoint that is used. This economy temperature setpoint can be adjusted on the temperature menu.

Heating engineer level
To access the heating engineer level, keep the «Warmer» and «Colder» buttons depressed and simultaneously roll the roller selector away from the display and then toward the display.
If the displayed temperature does not agree with the room temperature effectively
measured, the temperature sensor can be recalibrated (recalibration to be made on the
heating engineer level.)
The displayed temperature can be matched to the effective room temperature in increments of 0.2 °C (max. ± 2 °C).
Minimum setpoint limitation to 16 °C prevents undesired heat transfer to neighboring
apartments in buildings with several heating zones. The setting is to be made on the
heating engineer menu.
Optimization brings forward the switch-on point of the first heating period such that the
adjusted setpoint will be reached at the required time.
The setting depends on the type of controlled system, that is, on heat transmission
(type of piping system, radiators), building dynamics (building mass, insulation), and
heat output (boiler capacity, flow temperature).

REV23RF is a 2-position controller providing PID mode. The room temperature is controlled by the cyclic switching of an actuating device.
The controller generates the positioning signals depending on the deviation of the setpoint from the actual value acquired by the built-in temperature sensor.

HVAC Products 09.10.2003
The rate of response to the deviation depends on the selected control algorithm:
The controller is supplied with an active self-learning mode, enabling it to automatically
adapt to the type of controlled system (building construction, type of radiators, size of
the rooms, etc.). After a certain learning period, the controller optimizes its parameters
and then operates with the parameters it has learned.
In exceptional cases, where the self-learning mode may not be ideal, it is possible to
select PID 12, PID 6 or 2-Pt mode:
PID 12 mode Switching cycle of 12 minutes for normal or slow controlled systems
(massive building structures, large spaces, cast-iron radiators, oil
burners).
PID 6 mode Switching cycle of 6 minutes for fast controlled systems (light building
structures, small spaces, plate radiators or convectors, gas burners).
2-Pt mode Pure 2-position control with a switching differential of 0.5 °C (±0.25 °C)
for very difficult controlled systems with considerable outdoor tempera-
ture variations.
Protects the pump against seizing during longer off periods. Periodic pump run is activated for one minute every 24 hours at midnight. This function can be selected on the
heating engineer menu.
(Caused by the smaller inductive switching load of the relay, we recommend to control
smaller inductive loads only, like smaller pumps.)
Periodic pump run active:
/ periodic pump run inactive:
The controller is suited for cooling applications.
The function can be selected on the heating engineer menu.
The controller comes set for heating operation (refer to section «Factory settings»).
User-defined data:
Press the button behind the pin opening for at least one second: This resets the userspecific settings to their default values (heating engineer settings will not be changed).
The clock starts at 12:00. During the reset time, all sections of the display are lit, enabling them to be checked.
All user-defined data plus the heating engineer settings:
Press the button behind the pin opening together with the warmer and colder buttons
for at least one second.
After the reset, all factory settings will be reloaded (also refer to section «Factory
settings»).
Mechanical design
The REV23RF has a plastic housing with a large display and easily accessible operating elements. The controller is removed from its base by sliding it upward. It is thus
possible to replace the two type AA 1.5 V alkaline batteries contained in the compartment at the rear of the controller.
About 3 months before the batteries are exhausted, battery symbol
appears on
the display, but all functions are fully maintained. When replacing the batteries, the
current data will be retained for a maximum of one minute.
Plastic housing with easily accessible operating elements and removable cover. The
unit can be fitted to all commercially available recessed conduit boxes or directly on the
wall. A relay with a potential free changeover contact, the connection terminals and the
receiving antenna are integrated in the housing.
