The FLAGRO FV-THB {15m} is a remote thermostat accessory designed for use with Flagro indirect fired heaters in temporary heating applications. It features a 50-foot cord with a twist lock connection, allowing technicians to monitor and control heat output from a safe distance without approaching the heater unit directly. The extended 50-foot cord length distinguishes this model from the standard FV-THB, which uses a 25-foot cord. The ambient operating temperature range is 40 to 100 degrees F. Licensed HVAC technicians and temporary climate control professionals are the primary installers of this accessory.
This thermostat is suited for temporary heat applications where ambient temperature regulation is required at a distance from the heat source. It is commonly deployed on commercial construction sites, industrial enclosures, and temporary structures requiring controlled heat management during cold-weather job-site heating seasons. The male plug end and twist lock connector allow for straightforward field hookup without specialized tools.
Designed for use with Flagro indirect fired heater units that accept a remote thermostat with twist lock connection. The standard FV-THB variant is noted as compatible with THC 175DF and THC 355CDF models. Confirm heater model compatibility before installation, as thermostat fitment is specific to heater control circuit design.
Installation is typically performed by HVAC technicians or qualified temporary climate control professionals. Power down and disconnect the heater unit from its power source before connecting or disconnecting the thermostat cord. Ensure the twist lock connection is fully engaged before restoring power. Follow all applicable site safety protocols and manufacturer operating instructions during setup.
