Secure SRT321 User And Installation Instructions Manual page 10

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.
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.
Now ensure that the system is
responding to the ON/OFF commands
from the Room Thermostat and explain its operation to
the householder before handing over these User
Instructions.
