Symmons TempControl HTA-100 Installation And Service Instructions

Brand: Symmons

Model: TempControl HTA-100

Type: Installation And Service Instructions

Symmons TempControl HTA-100 is a high-temperature audio-visual alarm system designed to monitor and control warm or hot water temperature, alerting you when it exceeds a preset limit. It features:

Temperature monitoring: The system monitors water temperature using a temperature probe, alerting you when it approaches or exceeds a set caution or alarm temperature.
Audio-visual alarms: When the caution set point is reached, the system emits a brief audible signal and blinks an amber LED. If the alarm set point is reached, it triggers a continuous audible signal, blinks a red LED, and turns off a green LED indicating normal operation.

High Temperature Audio Visual Alarm System, HTA-100

Installation and Service Instructions

TempControl

General Information

■ Alarm System - TempControl High Temperature Audio

Visual Alarm System will monitor, alert and alarm when

water temperature exceeds preset limit. It best ts

applications where there is a critical need to accurately

monitor and control warm or hot water temperature.

■ Solenoid Valve (optional) - When alarmed, the valve is

de-energized and closes to provide complete shutdown of

the water ow.

■ Relay (customer supplied option) - Installed relay enables

remote monitoring of alarm control module.

■ Caution Set Point - is the lower of the two set point

temperatures that alerts when the output water is

approaching an undesirable temperature limit.

■ Alarm Set Point - Once the output temperature reaches the

alarm set point, the system goes into full alarm mode.

Installation

Important: All piping should be thoroughly

ushed prior to installation to prevent debris from

interfering with the solenoid operation. Do not run

solenoid power and temperature probe through

same conduit.

Piping

■ Tee Fitting - Required; appropriate size tting for

application purchased seperately (see options).

■ Temperature Probe - Locate probe as far downstream from

mixing valve as is reasonably possible.

a. Slide connector nut and ferrule piece over the probe.

b. Slide probe 1/2” to 2/3” into the tee tting.

c. Slide the ferrule and connector nut down the probe sha

and tighten in place.

■ Solenoid Valve (optional, 12 VDC, 10 Watts, normally

closed) - Install valve directly before the temperature probe in

any orientation. Make note of the correct direction of the water

ow as marked on the valve.

Electrical

■ Mount the 4" x 4" supplied mounting box in a dry location

within wiring reach of the temperature probe and solenoid

valve if used.

■ Mount supplied transformer.

For California Residents

WARNING: is product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.

It may be necessary to move the opposite set point to

achieve the desired setting. Once the desired temperatures

are selected, return the key to the RUN position.

Alarm Lockout

e alarm control module can be locked to prevent changes to

the set points, even with the access key.

■ Once caution set point and alarm set point has been set,

remove the screws from upper right and lower le corners of

front plate. Remove the control module from the 4" x 4" box.

■ Enable set point lockout

Enable

- DIP Switch 2 = ON

Disable - DIP Switch 2 = OFF

■ Reinstall the control module into

the 4" x 4" box.

■ When the key is placed in the SET

position, the display will alternate

between a set point temperature

and the characters LOC.

■ Set point temperatures can be viewed but unable to change.

Alarm Operation

Normal Mode:

■ Green Valve (normal) LED  LED is lit to indicate

normal operation; that water temperature is below set

point temperature

and can ow. If optional solenoid valve

is installed, it is in the open position.

■ Flashing Red Dot



A ashing red dot (Heart Beat)

in the lower right corner of the display indicates that the

systems processor is running.

Caution Mode:

■ Amber Caution LED  LED will blink and the audible

signal will sound briey every 60 seconds when the

temperature reaches the caution set point indicating

attention should be paid to the system.

■ Green Valve (normal) LED  LED will remain lit

indicating normal operation.

Alarm Mode:

■ Red Alarm LED



LED will blink and the Amber

Caution LED

 will go out if the output temperature

reaches the alarm set point. A continuous pulsing audible

signal will also be heard.

■ Green Valve (normal) LED  LED will go out indicating

no water can ow. (If solenoid is installed, valve will close)

Signals mean immediate attention should be given to the system.

Alarm Hysteresis:

■ Amber Caution LED  LED will light if the temperature

decreases below the alarm set point indicating that the

temperature is lower than the alarm set point but still

greater than the caution set point.

Alarm condition/mode will still be in eect. e system

will only reset when the temperature decreases below the

caution set point.

■ Relay (customer supplied option) -

Connect relay coil wires

between the relay and the valve power output terminals on

the back of the control module as identied in Figure 2. Note

that there is no polarity required between connections.

Fahrenheit / Celsius Temperature Display Setting

■ Select either Fahrenheit or Celsius

display units by setting Dip Switch

on control module circuit board.

Fahrenheit

DIP Switch 1 = OFF

Celsius

DIP Switch 1 = ON

Electrical Enclosure Box

■ Secure control module in electrical box using the two (2)

screws provided with box. Screws should be inserted into the

upper right and lower le corners of the control module.

■ Do not remove upper le and lower right screws securing the

control module together.

Temperature Set Point Adjustments

NOTE: The following settings were set at the factory:

Caution Alert Temperature = 114˚F (45.6˚C)

High Limit Alarm Temperature = 120˚F (48.9˚C)

■ Reset temperature

settings

- Reset the above

factory temperature

settings as required by

the application to prevent

erratic temperature

readings that can

prematurely activate the

alarm.

■ SET key position - Turn

key from the RUN position

to the SET position.

■ Identify caution set

point temperature (A)

Press SELECT keypad

button until A appears in the rst eld of the LED display.

e three (3) digits immediately following the A identies the

current caution set point temperature.

■ Set caution set point temperature - Pressup



down

keypad arrow buttons located below the display to increase

or decrease temperature setting.

■ Identify alarm set point temperature (H) - Press SELECT

keypad button until H appears in the rst eld of the LED

display. e three (3) digits immediately following the H

identies the current alarm set point temperature.

■ Set alarm set point temperature - Press up



down

keypad arrow buttons located below the display to increase

or decrease temperature setting.

NOTE: Caution set point temperature cannot be set higher

than alarm set point temperature and alarm set point

cannot be set lower than caution set point temperature.

Override Key

Alarm Set Point - once alarm set point temperature has been

reached, only personnel with the override key can initiate water

flowing in the system.

■ Override Position - Insert the key into the control module

front panel and turn the key switch to the override position.

e solenoid valve is held open allowing water to ow.

All users should be clear of the water ow due to

excessive temperature owing until the system is

corrected.

■ SILENCE Keypad Button - e audible signal may be

silenced by depressing the SILENCE keypad button located

on the panel. e audible signal will only be silenced for 60

seconds and will resume at the completion of the cycle.

■ Key Removal - e key cannot be removed in the override

position

preventing the solenoid from being held open and

le unattended.

■ Alarm Hysteresis - As the system output temperature is

corrected, the above Alarm Hysteresis conditions will occur.

■ Green Valve (normal) LED



LED will blink and an

audible signal will be heard regardless of the current mode

when the key switch is in the override position and the

silence period has expired.
