1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your Roth Basicline H 230 V Room Thermostat, model 1135007402. This wired room controller is designed for manual temperature regulation, primarily for floor heating systems, operating on a 230V AC power supply.
Please read this manual thoroughly before installation and use to ensure safe and efficient operation of the device.
2. Safety Instructions
- Electrical Hazard: Installation and wiring must be performed by a qualified electrician in accordance with all local and national electrical codes.
- Disconnect Power: Always disconnect power to the circuit at the main breaker or fuse box before performing any installation, wiring, or maintenance.
- Voltage: This device operates on 230V AC. Ensure the power supply matches this requirement.
- Intended Use: Use this thermostat only for its intended purpose of controlling room temperature, specifically for floor heating systems.
- Environmental Conditions: Do not expose the device to moisture, extreme temperatures, or corrosive environments. The device has an IP30 rating, meaning it is protected against solid objects larger than 2.5mm but has no protection against liquids.
3. Product Overview
The Roth Basicline H 230 V Room Thermostat is a compact, white, rectangular device designed for wall mounting. It consists of a front cover (not shown disassembled) and a base unit containing the electronic components and wiring terminals.
Figure 1: Internal view of the Roth Basicline H 230 V Room Thermostat, showing the mounting plate (left) and the electronic module with terminal block and adjustment potentiometer (right).
Key Components:
- Mounting Plate: The left part of Figure 1 shows the backplate with mounting holes for secure wall installation.
- Terminal Block: Located on the right part of Figure 1, this grey block provides screw terminals for electrical connections (power input, load output, external setback).
- Adjustment Potentiometer (P1): A blue component with a screw adjustment, labeled P1, visible on the circuit board. This is used for fine-tuning or setting specific operational parameters, possibly related to temperature range or calibration. Markings around it indicate values like 5, 10, 15, 20, 25.
- Control Label: An internal label provides essential product information, including model number, voltage, load specifications, and manufacturer details.
4. Setup & Installation
Before beginning installation, ensure the main power supply to the installation area is switched off.
4.1 Mounting
- Separate the front cover from the base unit (if not already separated).
- Position the base unit (mounting plate) on the wall at the desired location, ensuring it is away from direct sunlight, drafts, or heat sources that could affect temperature readings.
- Mark the drilling points through the mounting holes on the base plate.
- Drill holes and insert appropriate wall plugs.
- Secure the base unit to the wall using screws.
4.2 Wiring
Refer to the internal wiring diagram on the product label and Figure 1 for terminal identification. All wiring must comply with local electrical regulations.
| Terminal Number | Label (from OCR) | Description |
|---|---|---|
| L | L | Live (Phase) input for 230V AC power supply. |
| N | N | Neutral input for 230V AC power supply. |
| Load | Last | Output to the heating element (e.g., floor heating actuator). Connect the switched live wire here. |
| External Setback | ext. Absenkung | Input for an external signal (e.g., from a timer or central control system) to activate a temperature setback mode. Consult your heating system documentation for specific connection details. |
- Connect the Live (L) and Neutral (N) wires from your 230V AC power supply to the corresponding terminals.
- Connect the switched Live wire for your heating load (e.g., floor heating actuator) to the "Last" terminal. The Neutral for the load should typically be connected directly to the main Neutral.
- If using an external setback function, connect the appropriate control wires to the "ext. Absenkung" terminals.
- Ensure all connections are secure and wires are properly insulated.
4.3 Initial Configuration (Potentiometer P1)
The potentiometer P1 (blue component on the circuit board) may be used for initial calibration or setting a temperature range. The markings (5, 10, 15, 20, 25) suggest a range adjustment. Typically, this is set during installation by a professional to match the specific heating system requirements or desired temperature limits. Consult your heating system installer or Roth technical support for guidance on setting P1.
After wiring and any initial configuration, carefully reattach the front cover to the base unit.
5. Operating Instructions
The Roth Basicline H 230 V Room Thermostat features manual control for setting your desired room temperature.
- Temperature Setting: The thermostat typically has a rotary dial or buttons on the front cover (not visible in the internal image) to adjust the desired temperature. Rotate the dial or press the buttons to increase or decrease the setpoint.
- Heating Indicator: A status LED (if present, not explicitly visible in the internal image but common for thermostats) will illuminate when the heating system is active (i.e., when the thermostat is calling for heat).
- External Setback Function: If connected, an external signal to the "ext. Absenkung" terminals will activate a pre-set setback temperature, typically lower than the comfort temperature, for energy saving during unoccupied periods. The specific setback temperature is usually fixed or configured during installation.
For precise temperature control, ensure the thermostat is not obstructed and has good air circulation around it.
6. Maintenance
- Cleaning: Clean the exterior of the thermostat with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray liquids directly onto the device.
- No User Serviceable Parts: The thermostat contains no user-serviceable parts. Do not attempt to open or repair the device yourself, as this will void the warranty and could pose an electrical hazard.
- Regular Checks: Periodically check that the thermostat is securely mounted and that there are no visible signs of damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat not turning on. | No power supply. | Check the main circuit breaker or fuse. Ensure wiring connections are secure. |
| Heating system not responding. | Incorrect wiring; thermostat set too low; heating system fault. | Verify wiring connections (refer to Section 4.2). Increase the set temperature. Check the heating system for other faults. |
| Room temperature is inaccurate. | Thermostat location affected by drafts or heat sources; P1 potentiometer misconfigured. | Relocate the thermostat if possible. Consult a professional to check or adjust the P1 potentiometer setting. |
| External setback not working. | Incorrect wiring for external setback; external signal not active. | Verify wiring to "ext. Absenkung" terminals. Check the external control device. |
If you are unable to resolve an issue after following these steps, please contact Roth customer support or a qualified technician.
