TempTracker mod+ Hybrid Installation and Operation Manual

HTC# 059105-00D
• The System Output relay will remain active until the System Run-On Delay expires and then it will turn off.
• When Setback is selected in the Startup, a BMS/EMS or external clock can provide a Setback signal using these
Setback is selected from the Shutdown/Tstat/Setback mode in the Startup menu.
• Bring the two wires from the dry contact to the terminals marked
SHUTDOWN/TSTAT/SETBACK- 31,32
.
• The signal must be a dry contact only. No voltage can be placed across the
SHUTDOWN/TSTAT/SETBACK
terminals.
Wiring the prove
(Terminals 29, 30)
• The Prove feature is provided to check system component operation and must be selected in the Startup Menu
from the Prove/DHW Sharing menu. See "Prove/Indirect Domestic Hot Water (DHW) Priority" on page 25.
• A typical use of this feature is to check for pump flow or combustion air damper status before firing any boiler.
• If the PROVE input is open on a call for heat, the TempTracker mod+ Hybrid will enable only the System Output.
All boiler outputs will be off when the
PROVE
input is open.
• A factory-installed jumper provides the System Prove signal. Do not remove the jumper unless it will be replaced
by a System Prove signal or these terminals are to be used for DHW call input.
• Bring the two wires from the dry contact to the terminals marked
PROVE - 29, 30
.
• Prove Input terminals can accept a dry-contact signal only. No voltage can be placed across these terminals.
WarnInG
The PROVE input cannot be used as a safety limit. All equipment must have its own
certified limit and safety controls as required by local codes. If Prove is selected in the
startup menu, no boiler stage will start unless Prove terminals are shorted. DO NOT
remove the PROVE jumper supplied unless replacing it with a Prove signal.

Wiring the Indirect domestic Hot Water (dHW) call
(Terminals 29, 30)
• DHW can be used to raise system Set Point to the DHW Set Point as well as manage the System Pump according
to the DHW Priority setting. One of the DHW options must be selected from the Prove/DHW Sharing Startup
menu. See "Prove/Indirect Domestic Hot Water (DHW) Priority" on page 25.
• Wire an aquastat or a control to provide dry-contact closure on the
DHW Call
- 29, 30
terminals.
• Remove the jumper on the
DHW
terminals for proper operation.
• DHW Call terminals can accept dry contact signals only. No voltage can be placed across these terminals.

Wiring the system output
(Terminals 3, 4)
• The SYS output relay will energize and remain constantly energized whenever the outdoor temperature is below
the Outdoor Cutoff.
• When the outdoor temperature rises 2°F above the Outdoor Cutoff, the SYS output will remain energized for the
period set by the System Run-On then de-energize. See "System Run-On" on page 33.
• In addition, the System output will energize during summer DHW calls when DHW No Priority is selected. See
"Prove/Indirect Domestic Hot Water (DHW) Priority" on page 25.
• The SYS output has one Normally Open (N.O.) relay contact rated for (1/8 HP).
• The N.O. contacts are dry contacts only. They do not source any voltage.
• Class 1 voltages must enter the enclosure through a different opening from any Class 2 voltage wiring.
