Product Description; Installation Guidelines - Secure SEC_SRT321 Quick Start Manual

Product description

The SRT321 is a battery operated wall thermostat. Using a big wheel on the device the user can preset the desired
target temperature in the room. By verifying the target temperature with the measured real temperature closed to
the device the unit decides how to operate a wirelessly attached power switch that is attached to the heater. In
parallel a central gateway of Z-Wave control software can set the target temperature using Z-Wave. This enables to
realize a time scheduled zone heating. The thermostat itself does not have any internal timers but executes the
wireless settings (COMMAND CLASS THERMOSTAT_SETPOINT) and the local setup.
Batteries
The unit is operated by batteries. Use only batteries of correct type. Never mix old and new batteries in the same
device. Used batteries contain hazardous substances and should not be disposed of with household waste!
Battery Type: 2 * AAA

Installation Guidelines

Choose a suitable mounting position in your room for installing the device. The SRT321 should be mounted on an
internal wall approximately 1.5 metres from floor level using the wall plate provided and should be in a position
away from draughts, direct heat and sunlight. Ensure that there will be enough space to allow easy access to the two
retaining screws located at the base of the wall plate. Avoid installing the thermostat against or behind any large
metal surfaces which could interfere with the radio signals.
Offer the plate to the wall in the position where the SRT321 is to be mounted and mark the fixing positions through
the slots in the wall plate. Drill and plug the wall, then secure the plate into position. The slots in the wall plate will
compensate for any misalignment of the fixings. Undo the screws of the base of the thermostat and swing it away
from the wallplate. Place the 2 x AAA batteries correctly into the battery compartment. Complete the installation by
swinging the room thermostat into position by engaging with the lugs at the top of the wall plate before pushing it
carefully into its plug-in terminal block. Tighten the 2 captive screws on the underside of the unit.
