between the furnace and any
combustible surface. This permits the
heat from the case surface to escape
so as not to create a possible fire
hazard.
Site Selection
Install furnace on a sturdy surface and allow adequate
space for ventilation.
Electrical Connections
The electrical specifications are located on the specification
plate on the back of the furnace. Consult Thermo Scientific
if your electrical service is different than those listed on the
specification plate. Prior to connecting your Type 1500 furnace
to your electrical supply, be sure the two position power switch
is in the OFF position.
Your 120V Type 1500 furnace may be wired either directly
through a conduit system or by using a power cord and
plug which conforms to the National Electrical Codes and
electrical code requirements of your area.The terminal
block to be used in wiring is located on the lower rear of
the furnace. For 120V supply connections, use 14 AWG
or larger wires suitable for at least 105°C (221°F).
Warning
To avoid electrical shock, this furnace
must be installed by a competent
electrician who ensures compatibility
among furnace specification, power
source and ground code requirements.

SINGLE SETPOINT MODEL W/OTP
20° above your working temperature to provide
protection for your workload. In addition to over
temperature protection, units containing a single
setpoint controller w/OTP feature a mechanical OTP
relay device, which disconnects power from the
elements in an alarm condition.
Tuning
This controller incorporates a self-tuning feature, which
determines the optimum control parameters for the
best temperature accuracy with your load and setpoint.
Use this feature the first time you use your furnace and
each time you change either your setpoint or the type
of load you are heating. Thermo Fisher Scientific
recommends you use this feature to provide the best
temperature accuracy the controller can attain. To use
the tuning feature:
1. Start tuning with the process at ambient
temperature. This allows the tuner to calculate
the low cutback and high cutback values
more accurately.
2. Adjust the setpoint to your desired value.
3. Press the SCROLL button until display reads,
“A.TUNE.”
4. Press the UP or DOWN button to select, “on.”
5. Press the PAGE button to return to the HOME
DISPLAY. The display will alternately flash
between “tunE” and the HOME DISPLAY while
tuning is in progress.
6. The controller will then turn the heating on and
off to induce an oscillation. When the
measured value reaches the required setpoint
the first cycle will end.
7. Tuning will be complete after two oscillation
cycles and then the tuner will turn itself off.
8. Normal control function will resume after the
controller calculates tuning parameters.
Note:
Furnace must be at ambient
temperature before starting a tune.
“Stat” and “Sp.rr” must be set to OFF or
“tunE” will not initiate.
Note:
Tune has completed when “tunE”
stops flashing on display.

Note
These instructions are used with the Single Setpoint models with OTP only
(See models listed on front page).
Functions
This type of controller has single ramp and dwell
programming capabilities. The Ramp and Dwell can be
configured to five different modes.
Mode 1 (Opt. 1)
Mode 2 (Opt. 2)
Mode 3 (Opt. 3)
1. Mode 1 (DWELL) The dwell time begins once
the setpoint reaches the set threshold. The
END TYPE action is executed when the dwell
timer reaches the end.
2. Mode 2 (DELY) The timer starts immediately
upon instrument power-up, or when run is
selected. The instrument remains in standby until
the time has elapsed. After the time has elapsed,
the instrument controls up to setpoint.
3. Mode 3 (SF.ST) Starts automatically on power
up. This is a soft-start function. If the PV is
below the Soft Start Threshold, then the power
is limited to the Soft Start Limit until the
threshold is met.
