zone, and the dam

ers close to the zones that

are not callin

. The TZ-3

anel brin

s on the heatin

and conditioned air is delivered to the callin

zone

until that zone is satisfied. When the call is satisfied, the

stem enters the Pur

e mode. This holds o

en the dam

of the last zone callin

and

es into that zone. The

time can be set to three and one-half or two minutes. After

e, all dam

ers return to the O

osition.

zone thermostat can call for heatin

or coolin

. If there

are co-existin

calls for heat and cool, the

anel first acce

the first call. Once that call is satisfied, or a maximum of 20

minutes has ela

sed, the

anel switches to allow the o

osite

call.

On a call for heatin

or coolin

, the heat LED illuminates red

or the cool LED illuminates

reen. The zone dam

er LED

turns

reen for the zone callin

, and the dam

ers in the zones

not callin

close and turn red. As AOBD dam

ers move, the

LEDs turn amber.

Purge Mode

At the end of ever

call for heat or cool, the

anel enters a

Pur

e mode that holds o

en the callin

zone dam

er for three

and one-half or two minutes. Durin

this time, the

anel or the

HVAC e

ment can o

erate the fan. Pur

e also serves as a

time dela

nal that the

stem is in the Pur

e mode. Pressin

the

e override

button for two seconds overrides the Pur

e mode. Unless

there is a new call for heat or cool durin

the Pur

e mode, all

dam

ers are moved to the O

osition at the end of

Individual Zone Fan Control

When all zones are satisfied, the Fan switch of each

thermostat controls the fan o

eration for that zone. When the

Fan switch is in the On

osition, the fan is ener

ized, and the

dam

ers close to zones where the Fan switch is in the Auto

osition. If there is a call for heat or cool durin

this time, the

circulation mode ceases, and the heat or cool call is honored.

When the zone callin

is satisfied, the circulation call

resumes.

Single and Multi-Stage Operation

The

anel can control u

to three sta

Thermostat Operation

Conventional Thermostats

Conventional

(

R,W,Y,G

)

heat/cool thermostats can be used

with the TZ-3 to control sin

le or multi-sta

as, electric or oil

stems and heat

ment terminals are ener

ized for chan

eover use with

heat

Heat Pump Thermostats

HEAT PUMP THERMOSTATS WITH SINGLE Y OUTPUT

Heat

thermostats can be used if thermostat control of

2nd sta

e is desired. Thermostats that have a sin

le Y

terminal for first sta

e heat and cool can be used. When

selected, all thermostats must be similar.

If the thermostat ener

izes O on a call for cool, DIP switch 7

must be set to On and the O thermostat wire connected to W

on the thermostat connections for that zone. If the thermostat

ener

izes B on a call for heat, DIP switch 6 must be set to On

and the B wire connected to W on the

anel. In either case,

the O is alwa

s ener

ized to the e

ment in coolin

, and the

B is alwa

s ener

ized to the e

ment in heatin

IMPORTANT

Be sure DIP switches 6 and 7 are never both in the

On position.

HEAT PUMP THERMOSTATS WITH SEPARATE Y1 AND W1

TERMINALS

Use heat

thermostats with se

arate Y1 and W1

terminals for first sta

e heat and cool. Kee

DIP switches 6

and 7 in the Off

osition when thermostat O or B wire is not

used.

Emergency Heat Control

Emer

enc

heat is defined as usin

an auxiliar

heat source

without usin

the heat

. When the Em Heat switch or a

thermostat

uts the

anel in the emer

enc

heat mode, the

heat

is locked out and calls for heat are sent to the E

terminal.

A heat

thermostat can also control emer

enc

heat

from the thermostat s

stem switch. An L terminal ener

ized

durin

the emer

enc

heat mode is re

uired. The

recommended heat

thermostats all have hot L

terminals. See Table 1.

The two sta

e Em heat

er connects W2 and E. Jum

)

. The

er is located

below the e

ment terminals on the lower-left corner of the

anel.

Multi-Stage Thermostats

Use multi-sta

e thermostats to control two sta

es of heat via

W1 and W2 thermostat terminals. Control the third sta

e of

heat throu

h the sta

Rebooting Microprocessor

Certain conditions can han

the micro

rocessor. To reset

it,

ress and release the Boot button. The s

stem reboots and

enters the Pur

Discharge Air Temperature Sensor

The Dischar

e Air Tem

erature Sensor

(

not included

)

is a

-duct-mounted tem

erature

robe used to control

acit

and

revent over-heatin

or coil-icin

. The sensor

attaches to the TL terminals on the

anel.

Set the hi

h limit tem

erature on the maximum tem

erature

dial on the

anel, located left of the sta

e timer. See. Fi

. 19.

Set the tem

erature from 110 °F to 160°F in ten-de

ree

increments. The recommended settin

for fossil fuel/ electric

stems is 160°F

(

default factor

settin

. For heat

stems, the recommended settin

is 120F.

The coolin

tem

erature limit can be set at 40°F or 48°F.

Fig. 19. Maximum temperature dial.

IMPORTANT

Be sure the Discharge Air Temperature Sensor wir-

ing does not run parallel with line voltage wiring

unless more than 12 in. of separation exists or

shielded cable is used.

Use DIP switch 2 to chan

e coolin

limit settin

If the s

stem tri

s due to exceedin

a hi

h or low tem

erature

limit, the heatin

or coolin

stem shuts down and the fan

continues runnin

e the conditioned air from the

lenum.

When the low limit is tri

ed, the Cool LED flashes until it

resets. When the hi

h limit is tri

ed, the Heat LED flashes

until it resets.

Once the tem

erature recovers b

ten de

rees, the

ment run resumes.

Zone-A-Lone Switch

When the Zone-A-Lone switch is in the occu

ied

osition and

the OC/OC terminals are not used, the s

stem functions as a

normal zone control s

stem. When switched to the

unoccu

ied

osition, all dam

ers are o

ened and all re

uests

for heat, cool, or fan, exce

t from zone one, are not honored.

The zone one thermostat becomes the controllin

thermostat

for the entire s

stem. Durin

lon

unoccu

ied

eriods, one

thermostat can be set back instead of ad

ustin

each zone

thermostat in the buildin

The T8601D2027 and T8611G2051 include two OC terminals.

When wired to the TZ-3 OC terminals, and with the Zone-A-

Lone switch in the occu

ied

osition, the board enters the

unoccu

ied mode durin

the Leave and Slee

rams. This

feature re

uires two extra wires to the Zone 1 thermostat.

Circuit Breaker Protection

A built-in thermal circuit breaker

rotects the TotalZone

anel.

This circuit breaker

rotects the

anel a

ainst shorts in the

thermostat and dam

er wirin

and the remote occu

ied/

unoccu

ied switch. It does not

rotect a

ainst shorts in the

wirin

of the HVAC e

ment into the

anel.

When the circuit breaker is tri

ed, none of the LEDs

illuminate and the

ellow rectan

ular com

onent located to

the left of the TR1 and TR2 terminals is hot to the touch.

Remove

ower to the

anel for at least ten seconds to allow

the circuit breaker to cool off and reset. To eliminate the short,

verif

the dam

ers and thermostat wirin

Fan On In Heat

The s

stem blower can be set to come on with a call for heat

as re

uired for h

dro-air, heat

, or electric heat s

stems.

Set the blower usin

DIP switch 8.

TotalZone Add-A-Zone Panels

Usin

TotalZone Add-A-Zone Panels, the s

stem can be

anded to u

to 30 zones. There are three models: TAZ-1,

one zone; TAZ-2, two zone; and TAZ-3, three zone. Two wires

are re

uired to connect the TAZ to the TZ-3.

IMPORTANT:

When multiple panels are used, it is important that

the transformers be in-phase. Check the phasing by

measuring for 24V across the TR2 transformer termi-

nals on each panel. There should be 0 Vac. If not,

reverse the TR1and TR2 transformer wires on one of

the panels and recheck.

See Fi

. 13 and the TAZ installation instructions for more

information.
