This document shall:
– give you an overview of the new ranges RDG and RDF
– assist you by the selection of the suitable product, and
– provide you with helpful information for installation and commissioning
The section “application overview” for each main application – i.e. fan coil unit,
universal, heat pumps and VAV – shows what applications are covered by which
thermostat line.
The section “product overview” shows the available thermostat variants and their
supported applications.
Before you start
Before you start selecting a thermostat, we recommend to make the following
preselection:
– Type of main application: fan coil unit, universal, heat pump or VAV
– Application: e.g. 2-pipe with electrical heater
– Type of control output 1: ON/OFF, PWM, 3-position, or DC 0...10 V
– Type of control output 2: ON/OFF, PWM, 3-position, or DC 0…10 V
– Type of inputs: e.g. external room temperature sensor, changeover sensor,
