Thermostat Sourcing TBS 2300 (model 691215) — basic room temperature controller

The Sourcing TBS 2300 (model 691215) is a basic room temperature controller designed to maintain comfortable ambient conditions by switching heating or cooling equipment on and off according to a user-selected setpoint. Intended for straightforward temperature regulation in residential and light commercial environments, this thermostat provides essential functionality without advanced scheduling or network features. The device supports manual setpoint adjustment and simple on/off control for reliable operation of boilers, electric heaters, fan-coil units, or similar systems.

Advantages

The thermostat offers a compact and easy-to-use interface that enables quick setpoint changes and clear feedback on switching status. Its simple relay-based output ensures compatibility with a wide range of heating and cooling equipment. Low-complexity design reduces installation and maintenance demands, while mechanical robustness provides long-term basic control performance. The unit’s straightforward operation makes it suitable for users and installers who require dependable temperature regulation without complex configuration.

Suitable for

• Control of residential heating systems such as boilers and electric radiators
• On/off control of small commercial climate systems and fan-coil units
• Basic room temperature regulation in offices, apartments, and utility rooms
• Replacement of simple mechanical thermostats with an electronic controller

Key specifications

• Function: room temperature control with manual setpoint and on/off switching
• Output type: relay-based switching suitable for resistive and inductive loads
• Mounting: wall-mounted or surface installation in a room environment
• Power supply: mains-powered operation (observe local voltage and wiring standards)
• Control range: user-adjustable temperature setpoint within a typical comfort range
• Display and controls: simple mechanical or basic electronic interface for setpoint adjustment

How to use

Install the thermostat on an interior wall away from direct sunlight, drafts, doors, windows, and heat sources to ensure accurate ambient temperature sensing. Connect the relay output to the heating or cooling equipment following the device wiring diagram and local electrical regulations; power must be switched off during installation. After mounting and wiring, set the desired temperature using the thermostat’s adjustment control. The device will compare ambient temperature to the setpoint and switch the connected equipment on or off to maintain the selected temperature.

Usage recommendations

For consistent and accurate room temperature control, position the thermostat at eye level in the main occupied area, avoid mounting near heat-emitting appliances, and ensure proper electrical protection and correct load matching for the relay output. Regularly inspect wiring connections and clean the unit housing to prevent dust accumulation that could affect sensing accuracy.
