Use

To control the room temperature in individual rooms and zones that are:

· Heated or cooled with 2-pipe fan coil units

· Heated or cooled with 2-pipe fan coil units with electrical heater

· Heated and cooled with 4-pipe fan coil units

· Heated or cooled with compressor in DX type equipment

· Heated or cooled with compressor in DX type equipment with electrical heater

· Heated and cooled with compressor in DX type equipment

The RDF300… / RDF400… / RDF600... control:

· One 1- or 3-speed fan

· One or 2 on/off valve actuators

· One on/off valve actuator and one 1-stage electrical heater

· One 3-position valve actuator

· One 1-stage compressor in DX type equipment or one 1-stage compressor with

electrical heater

The RDF340… controls:

· One 1- or 3-speed fan

· One or 2 DC 0…10 V valve actuators

· One DC 0…10 V valve actuator and one modulating electrical heater (DC 0…10 V)

Used in systems with:

· Heating or cooling mode

· Automatic heating/cooling changeover

· Manual heating/cooling changeover

· Heating and cooling mode (e.g. 4-pipe system)

Functions

· Maintain room temperature via built-in temperature sensor or external room

temperature / return air temperature sensor

· Automatic or manual changeover between heating and cooling mode

· Select applications via DIP switches

· Select operating mode via the operating mode button on the thermostat

· 1- or 3-speed fan control (automatic or manual)

· Display current room temperature or setpoint in °C and/or °F

· Minimum and maximum setpoint limitation

· Key lock (automatic and manual)

· 2 multifunctional inputs, freely selectable for:

– Operating mode switchover contact (key card)
– Automatic heating/cooling changeover sensor
– External room temperature or return air temperature sensor
– Dewpoint sensor
– Electrical heater enable
– Alarm input

· Advanced fan control function, i.e. fan kick, fan start, selectable fan operation

(enable, disable or depending on heating or cooling mode)

· Purge function together with 2-port valve in a 2-pipe changeover system

· Reminder to clean filters

· Floor heating temperature limit

· Reload factory settings for commissioning and control parameters

· 7-day time program: 8 programmable timers to switch over between Comfort and

Economy mode (RDF400.01 / RDF600T)

· Backlit LCD (RDF300.02 / RDF400.01 / RDF600 / RDF600T)

· Optional infrared remote control ( RDF400.01 / RDF600T)

Applications

The thermostat supports the following applications, which can be configured by DIP
switches on the inner side of the thermostat’s front. Depending on the type, on/off or
modulating control outputs are available.
