USER GUIDE - NOVASTAT EL DIGITAL (RT- D)

Electronic thermostat with digital display for actuators 230VAC,

normally closed (NC) or normally open (NO)

MODES DESCRIPTION

Electronic thermostat with LCD display mode for water floor heating

systems controlled by actuators.

External pilot wire for night reduction.

Three Functioning modes: Comfort, Reduction or External CLOCK mode.

Possibility to regulate either the floor or room temperature, or combined (in

this case, the floor sensor is used as temperature limiter)

Silent (triac output), to be connected directly to actuators (see connecting

drawing on the installation sheet) or to our Modular connecting system. (In

this case please refer to the connecting box datasheet)

Use OK key to change the mode in the Operating mode menu

COMFORT operating mode:

Force comfort temperature operation

indefinitely.

By pressing (+) or (-) keys the comfort

temperature starts to blink and can be

adjusted.

The measured ( ) temperature

reappears after a few seconds.

OFF mode:

Use this mode if your Heating

installation needs to be turned OFF.

The display is blank. All Parameters

are saved.

ATTENTION: in this mode your

installation can freeze

REDUCTION operating mode:

Force reduced temperature operation

indefinitely.

By pressing (+) or (-) keys the comfort

temperature starts to blink and can be

adjusted.

The measured ( ) temperature

reappears after a few seconds.

External CLOCK mode:

The thermostat will follow the external pilot

wire signal. (as TIMER)

Blinking for indicate a comfort signal.

Blinking for indicate a reduced signal.

INSTALLATION PARAMETERS MENUS

Press the OK key during 5 seconds, Then use + or - keys to select the installation parameter to be adjusted.

Press OK to toggle the parameter setting or edit the value. If the value starts to blink you can use + / - keys to adjust this

value. Press + & - keys at the same time to reset this value to the factory default value. Once you have adjusted the

value press OK to validate this parameter value.

When you have finished, use + / - keys to go to 'End' display and then press OK key to exit installation parameter menu.
