OLIMPIA SPLENDID 9899 Thermostat User Manual
GENERAL INFORMATION
This integrated electronic regulation device is a digital thermostat for controlling the temperature in
rooms that are heated or cooled by fan coil units. It provides continuous, proportional control over
the valves and fan via 0..10V outputs, opening the former and regulating the speed of the latter so
as to ensure the room temperature is as pleasant as possible.
The device is also fitted with three ON/OFF relay outputs that can be used to control a fan with three
speed settings or two ON/OFF actuators. The room temperature can be monitored by the internal
or remote probe (optional).
DESCRIPTION OF CONTROLS
The controller is equipped with five control buttons.
(On/Off) button
Use this button to switch the controller on and off: when the controller is switched off the temperature
is not displayed, although some symbols may still be active, depending on the status of the outputs
If the controller is configured for the “Economy” function (P18), press the
button to activate/
deactivate this status according to the following diagram:
ON
OFF
(Speed) button
Use this button to modify the fan speed setting as desired.
Each time the user presses the button, the fan speed is modified in the following sequence:
where 1, 2 and 3 correspond to the three fixed fan speeds, while AUTO corresponds to the auto-
matic fan speed. More specifically, 1 corresponds to the lowest speed, 2 the medium speed and
3 the highest.
This means that, when the operator selects one of the above settings, when required, the fan will
always be activated at the corresponding speed.
If, on the other hand, the operator selects automatic speed, the greater the need to heat or cool the
environment, the higher the speed the controller activates the fan at.
If the controller is configured to control the fan via the 0..10V proportional output, it is to configure
the three fixed speeds to the desired values via the parameters C11, C12 and C13.
Parameter C10 may be used to customize the speeds, which can be recalled up by pressing the
button, and to enable the OFF function, which prevents the fan from being activated.
(Menu) button
Use this button to change the display readout mode: press once to display the set-point temperature.
In case the controller is configured to show the supply water temperature, press this button again
to display this value.
When changing the readout, the controller notifies the operator which temperature value is currently
displayed according to the following table:
Set-point temperature -
Supply water temperature
Press the button to cyclically to display the various temperatures. When inactive for a few seconds
the display reverts to the room temperature.
