TMC and Solenoid Valves
Temperature Monitoring Control
Application

When temperature monitoring is critical, the TMC brings greater peace of mind. In addition to providing an alarm whenever temperature reaches a critical point, when incorporated with a solenoid valve, the TMC effectively interrupts system activity until the problem is resolved.

TMC & Tempering Valve Combination Significantly Decreases the Risk of Scalding

The TMC is commonly used as an extra layer of protection in domestic hot water systems that use tempering valves. When temperatures reach a critical point in a domestic hot water system, the TMC activates an alarm and closes a solenoid valve, shutting down the flow of hot water into the system. Since the TMC includes an integral “latching” relay (manual reset), the problem must be resolved before the valve will open. In fact, two things must occur before normal operation resumes:

(1) The domestic water temperature must fall below the critical point

(2) The TMC’s manual reset button must be pressed. By resetting, you allow the solenoid valve (NC) to flow hot water to the tempering valve.

The TMC is also equipped with a second output for alarm. This output can be linked to the Heat-Timer Visual/Audio alarm, which uses both a red light and buzzer to indicate alarm status. It can also be linked directly into a Heat-Timer control panel, Notifact, or Energy Management System to provide remote alarm capability.

 

Features

The TMC is ideal for any application that requires vigilant system monitoring. Typical uses include:

  • Domestic hot water monitoring, especially in hospitals, nursing homes, and other commercial and institutional facilities
  • Low temperature monitoring, such as commercial or industrial refrigeration systems and freezers
  • Industrial applications which require tight monitoring of temperature, pressure, or humidity
  • Any space temperature monitoring which might require an alarm
Models

The TMC does not come with the solenoid valve.  Solenoid Valves must be ordered Separately.
