The DTS-HAZ digital thermostat kit is a microprocessor based temperature control and
power connection kit used for freeze protection or process temperature maintenance
of pipes or tanks protected by heat tracing
products. This thermostat can be used with
Constant Wattage, Mineral Insulated or Self
regulating heating cables in ordinary area or
Div 2 hazardous area locations.
The DTS-HAZ employs a Soft Start feature that
uses a proprietary software algorithm which
eliminates the inherent self-regulating in-rush
current, resulting in longer circuit lengths and
less nuisance tripping at cold temperatures.
Minimum operating ambient temperature is
-30˚F (-34.4˚C). The 100 Ohm platinum RTD is
provided with a 3 foot lead resulting in flexible
mounting options for the user.
This unit is designed to provide local pipe or
tank mounted temperature control and monitoring for heat traced pipes or tanks across a
variety of industries and applications.
Features
The DTS-HAZ provides easy programming of
the temperature set point, high and low temperature alarms and on/off control deadband
through the front panel push buttons. LED
indicating lights are provided for power to
the unit, heater power on and alarm status. A
normally open alarm contact (closure on alarm
condition and loss of power) is included for
wiring to your building management system to
indicate alarm status. This contact is opened
upon high or low temperature alarm, RTD
failure or loss of power to the system. The
loss of power indication qualifies this unit to
be used to sense temperature and control heat
trace used in fire protection systems. This
unit is programmable from -40˚F (-40˚C) to
485˚F (252˚C) set point and temperature alarm
points and will switch 30 amps of power.
• 6 inch by 6 inch box which houses the temperature control and monitoring unit along
with terminals for connecting instrument
power, heating cable and RTD.
• 100 Ohm platinum RTD which can be pipe
mounted or can be used to sense ambient
air temperature for control.
• Pipe stand off for direct pipe mounting and
termination of the heating cable directly in
the box. This feature reduces installation
time and labor cost both to terminate the
cable, and material, by eliminating the need
for a heat trace power connection kit.
