Commissioning

As

with

any

thermostat,

commissioning

ensures

that

the

thermostat

and

the

equipment

connected

to

it

are

operating

correctly

and

as

expected.

Although

the

SMT

‐

770

is

a

multifunctional

thermostat,

commissioning

is

quite

a

simple

process.

Follow

the

steps

detailed

below

and

use

the

troubleshooting

guide

on

page

44

if

you

encounter

a

problem.

When

the

thermostat

is

fitted

to

the

base

plate

and

when

24VAC

power

is

first

applied,

the

LCD

should

briefly

show

all

available

segments

(a

LCD

function

test)

then

display

the

software

version

number

before

showing

the

time

and

operating

mode

etc.

The

SMT

‐

770

is

fitted

with

a

number

of

safety

and

energy

saving

time

delays.

If

desired,

these

can

be

disabled

for

commissioning

purposes

by

entering

the

installer

mode

and

setting

the

CD=00

value

to

read

CD=01.

After

exiting

the

installer

menu

you

will

note

a

“Spanner”

icon

flashing

on

the

LCD

to

remind

you

that

commissioning

mode

is

Active.

After

commissioning

has

been

completed

it

is

important

to

disable

commissioning

mode

by

entering

the

installer

menu

once

again

and

setting

the

CD=01

value

back

to

CD=00.

Note

‐ 

when

in

commissioning

mode

ALL

time

delays

are

either

OFF

or

reduced

to

a

extremely

low

value,

it

is

therefore

normal

to

potentially

call

for

3

rd

stage

heating

almost

instantly

0.5deg

below

the

heating

set

point.
