2.0 Installation • Thermostat and Other Controls

WARNING

Electric Shock

Field wiring to the tube heater must be connected and grounded in accordance with national,
state, provincial, local codes and to the guidelines in the Tube Heater General Manual and
Series Insert Manual. In the United States refer to the most current revisions to the ANSI/NFPA
70 Standard and in Canada refer to the most current revisions to the CSA C22.1 Part I Standard.

Thermostat and Other Controls

The MP Series heater is designed to operate on various control configurations. The available control
options are:

A. Premium User Interface.
B. Potentiometer with On/Off switch.
C. Single-Stage Thermostat with optional room temperature sensor.

“A” Premium User Interface

The Premium User Interface (TH-PUI) is a smart logic controller that offers the optimal
performance out of your MP Series heater. It modulates the heater(s) with a full PID Controller
considering various inputs and outputs. It utilizes the current set temperature, the room
temperature (based on an on-board thermistor or an externally connected zone sensor), mode
selected, and other items to set the speed of modulation. Therefore, the heater output immediately
responds to a change in air temperature. For installation of this device, see Figure 2.2 on Page 10.

“B” Potentiometer

A linear 10k Ohm potentiometer can be used as a control device for the MP Series. This allows
the user to manually control the heaters firing rate based on the dial position. The heater will
modulate in increments of 1%, and vary from minimum firing rate to the full firing rate. An On/Off
switch or timer is necessary to allow for the heater to shut off. For installation with this device,
see Figure 2.3 on Page 11.

“C” Single-Stage Thermostat

A single stage heating thermostat can be used as a control device for the MP Series. This allows
the user to utilize a desired field supplied thermostat that best suits their individual needs. The
heat control is designed for use with a 2-wire heating system, (R & W) and is low voltage. The
heater cannot power the thermostat. The thermostat selected must not have a heat anticipator. For
installation with this device, see Figure 2.4 on Page 12.

When using a single stage thermostat, the use of a zone sensor is highly recommended. The unit will operate
without this accessory, but will then only modulate based on a predetermined algorithm that considers cycle
timing and history. Therefore the heater will not respond to rapid changes in air temperatures.

NOTICE

2.0 Installation • Thermostat and Other Controls • Zoning Heaters • Control Devices

MP Series

Zoning Heaters and Configuring ‘Master/Slave’ Heaters

The MP Series is designed to allow for several heaters within the same zone to simultaneously modulate
in synchronization when connected to a single control device. This configuration requires one ‘Master’
heater that is connected directly to the heat control device, and the remaining ‘Slave’ heaters are to be
wired to the ‘Master’ heater. The ‘Slave’ heaters will modulate based on the control signal from the
‘Master’ heater. During the operation of the system, all the ‘Slave’ heaters will modulate at the same
percentage rate of the full input as the ‘Master’ heater.

When wiring multiple heaters together for zoning, the heaters must be wired in series with a ‘Master’
heater utilizing a shielded thermostat wire. Connect the heaters via the appropriate wiring diagram. See
Pages 9-12 for more information.

Building Management Systems and Other Remote Analog Signals

A Building Management System or a Remote Analog Signal may be used as a controlled device for the
MP Series. This allows the heater(s) to be controlled directly by the output of the Building Management
System directly dictates the heaters firing rate. The analog signal can be either 0-10VDC or 4-20mA.

A Premium User Interface (P/N: PUI) MUST be used in order to connect the Building Management
System to the heater.

2.0 Installation • Thermostat and Other Controls • Field Wring

Field Wiring

Field Supplied Control Wire: 18AWG plenum rated thermostat wire that is shielded w/ drain wire is

recommended for optimal performance.

Installing the Control Wire: Each heater includes a thermostat wire grommet to allow for thermostat wire
to be brought into the burner box. Insert the grommet into the low voltage wiring access hole. Feed the
thermostat wire through the grommet, piercing the rubber with the wire to ensure a tight seal. Ensure
enough wire length is available to make the proper connections. Tie the thermostat wire into a loose knot,
as shown in Figure 2.1. Ensure knot is loose enough to not cause any damage to the wire. This will allow
for a strain relief for the connections to the heater.

Figure 2.1 • Image for feeding the wire and showing the knot

Connections to the Heater: The control devices are connected to the Modulating Circuit Board (P/N:

TP-3250) via the thermostat terminal strips provided. The installer must select the appropriate thermostat
terminal strip to connect to the board depending on the control configuration desired. The unit will provide
the suitable voltage for each control device. DO NOT provide an external power supply to the thermostat
terminal strips. Damage to the circuit board may result and is not covered by warranty.

Three (3) thermostat terminal strips are included with each heater to allow for connections to the heater.
Note that only one terminal strip will be used for each application, as selected by the installer. The
remaining thermostat terminal strips can be discarded or kept with the manual for future reference.

• TP-3228 – 8 circuit terminal strip to be used with Diagram “A”.

• TP-3225 – 5 circuit terminal strip to be used with Diagram “B”.

• TP-3224 – 4 circuit terminal strip to be used with Diagram “C”.

Configuring the Heater

The MP Series heater utilizes DIP switches on the modulating controller to configure various options
available. The DIP switches are located under the modulating circuit board cover (See Figure 2.6), and
are labeled “Options” and “Address”. These switches have to be configured correctly in order for the unit
to properly function.

Figure 2.6 • Projected View of DIP Switches

Address DIP Switch

Options DIP Switch

‘Options’ DIP Switches

1 ‘Master/Slave’: This switch determines if the heater is a ‘Master’ or ‘Slave’.

• ‘Master’ Option: Selected if heater is stand-alone or ‘Master’ of a zoned system.

• ‘Slave’ Option: Selected if heater is a ‘Slave’ in a zoned system and is connected to a ‘Master’.

2 Outdoor Air Probe: This switch determines if an outdoor air sensing probe is installed (sold

separately, must be used in conjunction with a Premium User Interface).

3 Premium User Interface: This switch determines if a Premium User Interface (TH-PUI) is used as a

heat demand control device. (Use Field Wiring Diagram A - Figure 2.2 ).

4 Potentiometer: This switch determines if a linear taper 10K Ohm potentiometer is used as a heat

demand control device. (Use Field Wiring Diagram B - Figure 2.3).

5 Thermostat: This switch determines if a single stage thermostat is used as a heat demand control

device (Use Field Wiring Diagram C - Figure 2.4).

6 Economy Mode*: This switch determines if ‘Economy Mode’ is the desired mode of operation.

7 Standard Mode*: This switch determines if ‘Standard Mode’ is the desired mode of operation.

8 Comfort Mode*: This switch determines if ‘Comfort Mode’ is the desired mode of operation.

*If Premium User Interface is connected, the mode selection switches are inoperative. Modes are selected
from the controller. For more information on the modes, see Page 19.

Figure 2.7 • Standard Configuration of DIP Switches

*If outdoor air sensor is equipped, switch DIP#2 to the ON position.
Use Diagram “A” on Page 8 for connecting the Premium User Interface to the heater.

‘Address’ DIP Switches

The Address DIP Switches are only utilized in a ‘Master/Slave’ installation or for BMS configurations. All
other configurations ignore the settings of these switches. When addressing a heater for a ‘Master/Slave’
configuration, the ‘Slave’ heaters must be addressed for proper operation. Each ‘Slave’ must have its own
unique configuration, determined by the installer. Up to 256 unique combinations can be configured.

Setting the ‘Slave’ Heater(s): The ‘Slave’ heater configuration is set by selecting the ‘Slave’ position on
switch #1 in the “Options” DIP Switches. The address switches become active when the ‘Slave’
configuration is selected. On the Address DIP Switches, configure each heater so that each heater has its
own unique configuration. An example is provided below for a three heater zone system.

3.0 Operation

!

WARNING

This heater must be installed and serviced by trained gas installation and service
personnel only.

Do not bypass any safety features or the heater’s built in safety mechanisms will be
compromised.

Note: Reference the Tube Heater General Manual for installation requirements.

Sequence of Operation

There are two (2) main controllers for the MP Series heater. The TP-351A is the ignition controller, and is
responsible for the ignition sequence, flame monitoring, and safety lock-out features. The TP-3250 is the
modulating controller, and is responsible for the call for heat, modulating the gas valve and blower speed,
selecting the performance curve or mode, and handles various passive inputs and outputs for controlling
devices. These two devices will be referred to as their TP-#’s during the sequence of operation.

Standby:

TP-351A - 120VAC is held at the circuit of the circuit board.
TP-3250 - 24VAC and 120VAC is held at the circuit board.

Starting Circuit:

The TP-3250 checks various inputs to select the performance curve, model, and appropriate mode of
operation. After successful determination of all internal checks, the TP-3250 will output the conditioned
120VAC to the blower motor and 120VAC to the common side of the pressure switch.

Once operational static pressure is achieved, the differential switch will close, sending the 120VAC to the
TP-351A and the PS indicator light, initiating the ignition sequence. The glo-bar is energized with 120VAC
for 45 seconds from the TP-351A. Once the time is achieved, the TP-351A switches on the 120VAC for the
valve circuit and switches off the power to the glo-bar. The 120VAC from the TP-351A valve circuit is used
to power the coil side of the isolation relay and sends power to the TP-3250 to indicate the start of the
ignition sequence. The isolation relay switches 24VAC from the transformer to the primary coil of the gas
valve and valve indicator light.

Once the gas valve circuit is energized from the TP-351A, flame should be present on the burner and
visible through the sight glass. The flame rod monitors the burner flame through flame rectification, and
can be measured in micro-amps (this can be verified at the flame current test pins on the TP-351A).
Minimum required micro-amps are 1.0mA, and should be present during burner operation.

If the burner fails to light or flame is not detected within 8 seconds, the gas valve circuit is de-energized
and the control performs an “inter-purge” delay before attempting another ignition sequence. The control
will attempt 2 additional trials of ignition before entering the soft lock out sequence. In the soft lockout
sequence, the gas valve will be turned off immediately. After 1 hour, if the thermostat is still calling for
heat, the TP-351A will automatically reset and attempt a new trial for ignition. After multiple attempts to
ignite the burner have failed, the TP-351A enters a hard lockout mode. The control will not open the gas
valve unless there is an intervention by the user. The reset can be done by either resetting the thermostat
or removing the 120 VAC for a period of 5 seconds.

18

MP Series

3.0 Operation • Sequence of Operation • Performance Curves

Running Circuit:

After ignition, the flame rod continuously monitors the flame presence. If sense of flame is lost for a time
of 1.0 seconds or greater, the TP-351A closes the gas valve circuit and a new trial for ignition sequence is
initiated.

Modulating Circuit:

Pre-heat – During the ignition sequence, the TP-3250 operates the blower and gas valve at 100% operation
to optimize ignition. Once ignition is established, the heater will enter a pre-heat cycle for 90 seconds,
operating the blower motor and gas valve at 100%. However, if the heater has cycled in the previous 5
minutes, the controller will skip the pre-heat cycle, and go straight to modulating operation.

The blower motor and modulating coil on the gas valve are energized directly from the TP-3250
modulating controller. The controller utilizes PID logic to match the selected performance curve to the
heater’s operation. Based on the determined system configuration, the control will operate as needed to
match the desired system performance.

Performance Curves

The MP Series is programmed to operate on several different performance curves. These curves are to
allow the user to select the desired operation that best accommodates their specific needs. The
performance curves can be selected either by the Premium User Interface (TP-PUI) or by setting the DIP
switches located under the control cover (Pages 14-15). The three modes are as follows:

• Economy Mode: Unit operates to maximize thermal efficiency.

• Comfort Mode: Unit operates to maximize perceived human comfort.

• Standard Mode: Unit operates as a balance between comfort and economy mode.

Economy Mode: Economy Mode is intended to maximize thermal efficiency. It is designed to provide a
system that is more thermally efficient than the other modes due to quicker dissipation of heat. This
mode is recommended for applications such as:

• Aircraft hangars

• Car washes

• Pole barns

• Foundries

• Unpopulated warehouses

Comfort Mode: Comfort Mode is designed to minimize temperature differentials across the length of
the heater. It is intended to provide a system that has a greater perceived comfort than the other modes
because of the reduction of extreme temperature zones. This mode is recommended for applications
such as:

• Patios

• Loading docks

• Break areas and lunch rooms

• Parts counters and service desks

• Golf driving ranges

• Woodworking shops

• Kennels

Standard Mode: Standard Mode is a balance between Comfort Mode and Economy Mode. It is
intended to provide a system that is moderately thermal efficient while still minimizing the greater
temperature differentials associated with economy mode. This mode is recommended for applications
such as:

• Populated warehouse heating

• Service garages

• Fire Stations

• Manufacturing

• Auto showrooms

3.0 Operation • Sequence of Operation • Diagnostics

MP Series

Shut-down:

When the thermostat is satisfied, the TP-3250 will de-energize the 120VAC power to the common side of
the pressure switch, de-energizing the thermostat circuit on the TP-351A. The blower motor will continue
to cycle for a period of 2 minutes for a post-purge cycle.

NOTE: Due to the PID Controller optimizing the output of the heater, the unit may run for a short period
after the call for heat has been satisfied.

For extended shut down periods:

Set external controller devices to off or lowest setting.

1

Turn OFF the 120VAC to the heater.

2

Turn OFF the manual shut-off valve in the heater’s gas supply line.

3

Prior to start up after seasonal extended shut-down, an inspection of the heater must be performed by

4

trained gas installation and service personnel. This will ensure optimal operation and years of trouble­free service.

Diagnostics

Lockout:

The controls will automatically lockout the heater system when an external or system fault occurs. There
are two types of lockout:

Soft Lockout: The heater will attempt to light three times. In the event of a failed ignition, (gas pressure,

valve, no flame sense etc.), the heater will enter a soft lockout period for 15 minutes and
then attempt to light three more times before entering a Hard Lockout mode.

Hard Lockout: If proof of flame is not established, a component failure occurs or blockages are evident,

the heater will enter hard lockout. If lockout occurs, the control can be reset by briefly
interrupting the power source. The control will not open the gas valve unless there is an
interruption by the user.
