3.3 UPPER LED READOUT (RED)
The default display of this readout is the temperature sensed at Probe 2, which is generally the supplied outlet
water temperature. Probe 2 may display the tank stored water temperature, flue gas temperature, ambient
temperature, remote tank, blended water temperature, etc., depending on the product and application. Refer to
your specific product’s Installation and Maintenance Manual and the supplied wiring drawing. The upper LED
readout can also be switched to display Probe 1 or 3(if used) or the modulation % or the temperature difference
between Probe 1 and 2. If set to display Probe 2, and Probe 2 is not utilized, the display will show “nu”.
By pressing and releasing the button once, the Upper LED will display the actual temperature sensed at
Probe 3. Probe 3 (if used) may display the flue gas temperature or outside ambient temperature, etc.,
depending on the product and application.
By pressing and releasing the button again, the Upper LED will display the modulation %. If the product is
a non-modulating product, the displayed valve should not be considered.
By pressing and releasing the button a third time, the Upper LED will display the difference between the
temperature sensed at Probe 2 (generally the outlet temperature) and the temperature sensed at Probe 1
(generally the inlet temperature).
To return to the default in the Upper LED readout, press the button to cycle back to the Probe 2
temperature.
All of the display information described above is available for monitoring through the optional MODBUS RTU
interface.
3.4 LOWER LED READOUT (YELLOW)
The default display of this readout is the temperature sensed at Probe 1, which is generally inserted into the
return inlet piping of the boiler. Probe 1 may display the tank stored water temperature, supplied outlet water
temperature, flue gas temperature, ambient temperature, remote tank or blended water temperature, etc.,
depending on the product and application. Refer to your specific product’s Installation and Maintenance
Manual and the supplied wiring drawing. The lower LED readout can also be switched to display Probe 2 or
3(if used) or the modulation % or the Time of Day.
By pressing and releasing the button once, the Lower LED display will show the Time of Day. Press again
to return to default display.
3.5 TO SET THE CURRENT TIME AND DAY (24 HOUR CLOCK)

6. RELAY OUTPUTS
6.1 OUTPUT SETUP AND SPECS
1. 3 relay outputs. SPST relay contacts going to spade terminals #4-9.
2. The outputs are rated at 3A, or 8A resistive load.
3. Each output (1-3) can be controlled via Modbus RTU Communication by setting on or off to the 1on, 2on, 3on
parameters.
4. Each output can be configured to operate as a control output, typically for temperature control. This is done when
1on, 2on, 3on respectively are set to rEG. This is the default setting.
a. 1on=rEG Output 1 is configured for Temperature Control (Same for 2on, 3on ).
b. 1on=oFF Output 1 is off.
c. 1on=on Output 1 is on any time the TempTrac is enabled (Alarms will not disable). On power loss, this contact
will be open, and when the TempTrac displays OFF, this will contact will be open. This is no longer a control
output, and is not subject to alarms.
5. Output 1, Spade terminals 4 & 5.
6. Output 2, Spade terminals 6 & 7.
7. Output 3, Spade terminals 8 & 9.
6.2 OUTPUT 1 CALL FOR HEAT (1on=rEG)
Kind of action: Heating
Reference probe: TP1
Terminals: SPADE 4 & 5
Related Parameters: St1, Hy1, LS1, US1, AC1, i3F, 1on
time
time
Out1
Probe1
Set1
Set1+ Hy1
NOTES
1. When probe 1 TP1 falls below St1, a call for heat output will occur.
2. Hy1 is the differential to prevent short cycling.
3. When Hy1 is negative, this will prevent the call for heat from starting until TP1 falls below St1 + Hy1. The call for
heat will continue until TP1 reaches or goes above St1. See chart above.
4. If Hy1 is positive, then the call for heat will start when TP1 falls below St1, and will stay active until TP1 rises
above St1 + Hy1. Not shown on chart.

Page 15/ 24 34-81 10/2013
6.3 OUTPUT 2 2ND STAGE (oS2=Std 2on=rEG)
Kind of action: Heating
Reference probe: TP1
Terminals: SPADE 6 & 7
Related Parameters: S2c, St2, Hy2, LS2, US2, AC2, oS2, 2on
time
time
Out2
Probe1
Set2
Set2+ Hy2
NOTES
1. Output 2 will function as an output temperature control when oS2=Std, otherwise output 2 is an alarm output
contact.
2. S2c determines if St2 is relative to St1 or independent. (S2c=dep or ind).
3. Hy2 functionality same as Hy1. See OUTPUT 1 CALL FOR HEAT.
6.4 OUTPUT 2 AS ALARM RELAY (oS2=AL, 2ON=REG)
1. Output 2 will function as an alarm contact when oS2=AL.
2. When an alarm condition occurs, Output 2 will be energized (relay closes) as an indication of an alarm condition.
3. Terminals: SPADE 6 & 7.

Page 16/ 24 34-81 10/2013
6.5 OUTPUT 3 TEMPERATURE PROTECTION (3on=rEG)
Kind of action: Heating
Reference probe: TP1 or TP2

Related Parameters: S3c, St3, Hy3, LS3, uS3, AC3, 3on, o3P
time
time
Out3
Probe2
Set3
Set3+ Hy3
NOTES
1. Output 3 can be used to enable pumps when temperature falls below a St3.
2. o3P will select the probe for Output 3. Pb1 or Pb2.

Page 17/ 24 34-81 10/2013
6.6 OUTPUT 3 ALTERNATE SET POINT
Kind of action: Heating
Reference probe: TP1 or TP2
Related Parameters: St3, Hy3, LS3, US3, AC3, St5, Hy5, 3on, o3P, SSE, AC5, ACA
NOTES
1. When SSE is enabled and Output 1 is in a de-energized state (off) Output 3 will function according to St3. When
Output 1 is in an energized state Output 3 will function according to St5.
2. ACA delays the change from St3 to St5.
3. o3P selects temperature probe to be referenced by Output 3.
4. Hy1, Hy3 and Hy5 are active but not shown in this illustration.

Reference probe: TP1
Related Parameters: S4c, St4, Sr, PS4, PP4, Ac4, i1S, i1t, i1F, i1d
NOTES
1. The kind of action of the modulation output depends on the sign of the Sr parameter.
2. If the parameter PS4 is different from nu, the percentage of the modulation output depends on the value set in
PS4, independently from the value of the probe. (0-100% represents 4mA to 20mA.)
3. If i1F=No and digital input 1 is ACTIVE, the analog modulation output is forced to the mA set in i1S parameter
independently from the value of the probe and the value of the PS4 parameters. After digital input 1 is no longer
ACTIVE, the analog output will stay at the actual mA value set in i1S for the time period set by at the i1t
parameter.
4. If the probe TP1 is broken, PS4=nu and the digital input 1 is off, the value of the modulation output depends on
the PP4 parameter.
5. The value of the PS4 parameter can be set directly by the keyboard. See par. 3.6.
6. Anti-short cycle delay for the analog output: when the analog output reaches the 4mA, it is held at 4mA for this
time. During this time the icon is flashing. When this delay has expired, normal functioning of modulation
output restarts. This delay will be reinitiated again after output 1 switches off.
7. Ranges: i1S (4-20 range) is actual mA, i1t (0-30 range) is seconds. PS4 & PP4 (0-100 & nu range) is percentage
of output 0%=4mA 100%=20mA nu=AUTO.

Page 19/ 24 34-81 10/2013
8. MODULATION BUFFER
Kind of action: Heating
Reference probe: TP2
Related Parameters: Th4, HY4
NOTES
1. This function references probe TP2 and will trigger output 4 to reduce the signal to 4mA when the temperature of
Th4 is reached by TP2 and hold it until TP2 drops below TH4+HY4. Output 4 then returns to normal operation
referencing TP1.
9. DYNAMIC RESET OF St1
Kind of action: Inverse
Reference probe: TP3
Related Parameters: tt, rr2, St1, rr1
If the outdoor temperature is lower than tt the dynamic reset of the St1 action starts as described in the following
diagrams.
Temper.
Outdoor
Temper.
Set1+rr1

NOTES
1. With rr1=0the dynamic reset of the set point 1 is disabled.
2. If the TP3 is not present (P3P=no) or broken, the dynamic reset of the set point 1 is disabled.
10. WARM WEATHER SHUT DOWN
The tt2 parameter, referring to the outdoor probe TP3, establishes the upper threshold which all the relay outputs are
open. Normal regulation restarts when TP3< tt2+Ht2.
To disable this function set tt2 to high a value. If the third probe is not present P3P=no, this function is disabled.
