Summary

1. Technical Description

Solar Charging

Solar circulation pump on/off controlled by temperature difference between collector and tank.

Speed Control

Solar circulation pump speed controlled via impulse packet control, adjustable 30-100%.

Sensor T3 (tank, upper half)

Measuring sensor for upper tank area, no switch function or diagnostics monitoring.

Balance Values

Display of minimum and maximum temperature values for sensors T1 and T2.

Manual Operation

Allows manual switching of input and output channels; returns to automatic after 8 hours.

Manual Lag Function

Sets a time lag for checking temperature values during manual operation.

Collector Cooling

Cools collector if tank temperature limit exceeded; pump switches off if T1 rises above standard value.

Tank Cooling

Reduces tank temperature to a preset lowest value, e.g., for vacations.

Vacuum Tube Collector Function

Enables solar heating system operation with sensor T1 in the collector connecting pipe.

System Messages

System messages for interrupted or shorted-out sensors displayed with symbols and correction steps.

Triac

Electronic on/off switch for 230V outputs, consists of 2 diodes switched anti-parallel.

System Protection

Stops solar charging if collector temperature exceeds set limit to protect system components.

2. General Safety Guidelines

Installer's Qualifications

Installation and commissioning must be by qualified installer; comply with national and local regulations.

Use and Application

Controlling solar thermal systems using applicable control patterns and additional functions.

Limitations of use

Check suitability for purposes other than solar thermal systems; guarantee lapse if unsure.

Guidelines for Installation and Operation

Mains disconnection, external switch, temperature limits, display placement, and system integrity checks.

3. Installation

Installation of the Case

Instructions for opening the control casing and mounting the unit to the wall.

Installation in the Solar Circulation Unit

Affixing the unit to the bracket, opening cable ducts, and routing cables.

4. Connecting Wires

General connection rules

Rules for flexible wires, tinning/crimping wire ends, and using PG9 screws.

230 V mains connection

Connecting mains power via ON/OFF switch; unit designed for 230V AC/50Hz.

Connecting the temperature sensors

Guidelines for extending sensor wires, using shielded cable, and connecting without regard to polarity.

Lightning protector module

Spike protection on sensor terminals; T1 requires SP2 box with excess voltage protection.

5. Operation

Display and Buttons

Explanation of display elements, symbols, and button functions for navigation and operation.

6. Information Menu

Collector temperature

Displays current, minimum, and maximum balance values for collector temperature.

Tank temperature, lower half

Displays current, minimum, and maximum balance values for lower tank temperature.

Tank temperature, upper half

Displays the current temperature of the upper tank area (sensor T3).

Operating hours

Displays total operating hours and allows resetting them.

Pump status indicators

Function display showing pump idle (off) or active (on) based on temperature difference.

7. Settings Menu

Temperature limitation tank, lower half (T max)

Sets the maximum temperature limit for the lower half of the tank.

Switch-on difference collector/tank (dT max)

Sets the temperature difference required to switch the solar circulation pump on.

Switch-off difference collector/tank (dT min)

Sets the temperature difference required to switch the solar circulation pump off.

Minimum temperature for analysis (T min)

Sets the minimum temperature for starting switch-on difference analysis.

Set point temp. difference for speed control (dT)

Adjusts the set point for speed control based on temperature difference.

Minimum pump speed (d min)

Sets the minimum speed percentage for the solar circulation pump.

Maximum pump speed (d max)

Sets the maximum speed percentage for the solar circulation pump (SECUSOL).

Charge time SECUSOL (T start)

Sets the charge time for SECUSOL systems at 100% pump speed.

8. Manual Operation Menu

Manual pump control

Allows manual switching of the solar circulation pump (output A1) on or off.

Manual operation lag time

Sets a lag time for manual operation mode returning to automatic mode.

9. Special Functions Menu

System choice

Selects the operating mode: Standard single-tank or SECUSOL system.

System Protection

Activates system protection and sets its start temperature.

Collector Cooling

Activates collector cooling and sets its start temperature.

Tank Cooling

Activates tank cooling and sets its switch-off temperature.

Tube collector function

Activates vacuum tube collector function and sets run time/switch-on value.

10. Service - System Messages

System Messages Overview

Displays system messages with caution symbols for errors and their corrections.

Interruption/Defunct Sensor

Indicates sensor or line connection interruption/defunct and correction steps.

Short Circuit Sensor

Indicates sensor short circuit and correction steps.

dT too high Warning

Indicates excessive temperature difference between collector and tank over 30 mins.

11. Service - Sensor Control

Pt1000 Sensor Resistance Table
