The WiFi Snow Melting Control 671 is designed to operate mechanical equipment to melt snow off an outdoor slab. It can
be used in hydronic or electric snow melting applications. This product uses a tekmar snow/ice detection sensor in order
to automatically melt snow using Pulse Width Modulation (PWM) and slab OutDoor Reset to maintain slab temperature.
It is capable of controlling a single boiler, steam valve, or electric cable to supply heat to the slab.

Dedicated Boiler A671-1 Mechanical
Description
The WiFi Snow Melting Control 671 operates a boiler that is dedicated for the snow melting system. The system is piped in
primary-secondary to allow constant flow rates through the low-mass boiler and filled with glycol to prevent freezing.
• The system pump operates continuously when heating the slab during melting/idling/storm operation.
• The boiler pump cycles on and off together with the boiler.
• The slab temperature is controlled by cycling the boiler on and off.
• The slab target is determined by the melting/idling/storm setpoint and by the measured outdoor air temperature.
The system operation is dependent on sensor selection, as listed in the table below.

Description
The WiFi Snow Melting Control 671 operates a snow melting zone warmed from a heat source that is shared with other loads
in a building. A heat exchanger isolates the glycol-filled snow melting system loop from the water-filled main heating system.
• The system pump operates continuously when heating the slab during melting/idling/storm operation.
• The slab temperature is controlled by cycling the boiler on and off.
• The slab target is determined by the melting/idling/storm setpoint and by the measured outdoor air temperature.
• A normally-closed aquastat protects the heat exchanger from freezing by shutting off power to the system pump.
The system operation is dependent on sensor selection, as listed in the table below.

Description
The WiFi Snow Melting Control 671 operates a steam valve and a steam-to-water heat exchanger to heat a glycol-filled snow
melting system.
• The system pump operates continuously when heating the slab during melting/idling/storm operation.
• The slab temperature is controlled by turning on and off the steam valve.
• The boiler relay is closed while the steam valve is open. This provides a signal to fire the steam boiler.
• The slab target is determined by the melting/idling/storm setpoint and by the measured outdoor air temperature.
The system operation is dependent on sensor selection, as listed in the table below.

Description
The system has two snow melting zones heated by two boilers. The water temperature is regulated by a shared mixing valve
for the two snow melting zones. The boilers and mixing valve are operated by a Universal Reset Module 423, Power Manager
346 and Mixing Expansion Module 444. Each snow melting zone is operated by a WiFi Snow Melting Control 671.
• The slab target is determined by the melting/idling/storm setpoint and by the measured outdoor air temperature.
• The zone pump cycles on/off when heating the slab during melting/idling/storm operation.
• When the zone is heated, the 671 communicates to the 423 and 444 to operate the mixing valve and fire the boilers.
•
The 423 and 444 close the mixing valve to provide boiler return protection when the boiler supply temperature falls below
the 423 boiler minimum setting.
The system operation is dependent on sensor selection, as listed in the table below.

Specifications
The following are the recommended specifications for the WiFi Snow Melting Control 671.
• The control shall have the ability to use a snow/ice sensor in order to automatically detect snow or ice and begin operation
of the system. The system shall continue to run until the sensor is dry or the control is manually stopped.
• The control shall have the ability to be manually started with an adjustable running time that counts down and automatically
stops the system.
•
The control shall not operate the system to provide heat to the snow melting zones when it enters into either a Warm Weather
Shut Down (WWSD) or a Cold Weather Cut Off (CWCO) mode.
• The system water temperature shall be based on the outdoor temperature and feedback from sensors located in the snow
melting slabs.
• The control shall have two separate access levels to limit the number of adjustments available to various users.
• The control shall have a manual override that allows each output to be manually turned on or off.
•
The control shall continuously monitor its temperature sensors and provide an error message upon a control or sensor failure.
•
The control shall record and display boiler and pump running hours and minimum and maximum temperatures depending
on the access level that has been selected.
•
During extended periods of inactivity, the pumps that are operated by the control shall be periodically exercised to prevent
seizure during long idle periods.
This Application Brochure is not intended to provide full installation instructions and safety information. In order to avoid property
damage or injury, please refer to the complete installation manual and product safety information provided with the product.
