The RH-1000 series uses the latest high accuracy RH & T element, the RH-1000 has options such as setpoint adjustment, momentary switch and fan speed selection, together with a multi-line backlit LCD display. A 0-10Vdc override status input option is also available, allowing occupancy indication on the display. 0-10Vdc, 0-5Vdc or 4-20mA (loop or externally powered) outputs for all measured values are available as standard. A custom output range for temperature can be requested, between –20 and +50°C. A directly connected passive thermistor temperature output is also available, as an alternative to the standard active temperature output. The -UN has a single output which automatically determines whether to run in current or voltage mode, no more jumpers or switches to worry about. This is also available with a directly connected passive output for temperature.
