1 General information 1.1 Introduction Thank you for purchasing a heating controller from Sauter. The equitherm EQJW 125 is a quality product from one of the leading manufacturers of controls products for heating, ventilation and air-conditioning. The equitherm EQJW 125 is a compact weather-compensating heating controller with switched outputs to control the flow temperature.
Access to SERVice and communication level Access to manual mode Normal mode corresponds to nominal mode as per EN12098-1. Back-up mode means that the heating is switched off. The anti-frost function is active. Sauter Components 7001029003 T8...
Display of setpoint temperature; flashing: display of actual temperature Display of flow temperature Display of outdoor temperature Display of room temperature Controller is in summer mode Calendar switching programme is currently active An error has occurred (see Section 6) Floor-drying (operational heating) is active Sauter Components 7001029003 T8...
3.1 Operating the device for the first time When you operate the equitherm EQJW 125 for the first time, you have to set the date and time. The controller is then basically ready to use. However, depending on the particular application, it may be necessary to change more settings after this.
'Heating medium pump output' option on the menu Push the input knob; select the menu option Turn the input knob; specify pump output (0= pump off, 1=pump on) Push the input knob; the setting is accepted Sauter Components 7001029003 T8...
Some of the parameters cannot be changed - they can only be viewed (version number, status information). 3.3.1 Accessing SERVice mode Set the rotary switch to the Service position Push the input knob Turn the input knob, display the code Push the input knob; the first SERVice parameter is shown Sauter Components 7001029003 T8...
Turn the input knob; the value for the parameter is changed Push the input knob; the new value is confirmed Push the ESC button to cancel the procedure. The value is not accepted unless it has already been confirmed. Sauter Components 7001029003 T8...
SP11 Correction of outdoor temperature The measured value for the outdoor temperature is adjusted with the help of this parameter. The value that is entered is added to the measured value for the outdoor temperature. Sauter Components 7001029003 T8...

Valves with a motorised actuator need a certain time (known as the valve run-time) to open or close completely. This SERVice parameter is used to set the equitherm EQJW 125 to the run-time for the valve drive that is being used. Optimal control quality and various protective functions are only ensured if the valve run-time is set correctly.

SP23, P24 Summer/winter or winter/summer time-change Thanks to the calendar time-switch integrated into the equitherm EQJW 125, the winter/summer time-change and the summer/winter time-change are carried out automatically. The date for the change-over is specified by the value for SERVice parameters SP23 and SP24.
3.4.2 Viewing the communication parameters Turn the input knob; select the communications parameter you want Push the input knob; the value for the parameter is shown BAUD To leave the value unchanged, push ESC to exit from the display Sauter Components 7001029003 T8...
BAUD Push the input knob; the new value is confirmed Push the ESC button to cancel the procedure. The value will not be accepted unless it has already been confirmed. Sauter Components 7001029003 T8...
0 = not enabled; 1 = enabled CP24 MOD bus via RS485 or MOD bus via modem: control station commands 0…1 expire after control station is inactive for 30 minutes 0 = not enabled; 1 = enabled Sauter Components 7001029003 T8...
If CP 12 is set to 1, this controller sends its current flow temperature (TF) setpoint on the device bus. CP13 Device bus: receive heat requirement If CP 13 is set to 1, the controller receives flow temperature requirement requests from the device bus. The mixer is then controlled to this temperature as a minimum. Sauter Components 7001029003 T8...

When CP24 = 1: if the controller is no longer receiving any Modbus enquiries, operating statuses specified via Modbus become invalid after 30 minutes and the controller operates independently of the control station again. If CP24 = 0, the operating statuses continue to have unlimited validity even beyond these 30 minutes. Sauter Components 7001029003 T8...
10. Service level and communication parameters; contains all the other parameters (heating characteristic, control parameters, communication settings, etc.) This is mainly needed for commissioning or in case of faults on the plant. Normal mode corresponds to nominal mode as per EN12098-1. Sauter Components 7001029003 T8...
( Section 6) can be added in case of a fault, • a display of the connection status can be added for modem operation. Press the ESC button once to go directly to the time display. Sauter Components 7001029003 T8...

... and you can now change it by turning it upwards or downwards (step value: 0.1°C). Push the input knob again to confirm the changed numerical value. Press the ESC button once before confirming to cancel the input; the old value is retained. Sauter Components 7001029003 T8...
Push the input knob; the time for the switching command is confirmed. Turn the input knob; select the mode for the switching command. Push the input knob; the mode is confirmed. Sauter Components 7001029003 T8...
Set the rotary switch to PROG Turn the input knob to go to the calendar programme Push the input knob; this selects the calendar programme. You see '_ _ _ _' or the first switching command if one is present. Sauter Components 7001029003 T8...
If the switching command was deleted, the next switching command is shown, or '_ _ _ _' if there are no more switching commands. For a change (SEt), the rest of the procedure is as described in the Section on 'Entering a switching command'. Sauter Components 7001029003 T8...
While the time is running down, the remaining time is shown in days, hours or minutes. After the temporary temperature change has finished, the heating circuit is again controlled in accordance with the automatic mode. N.B.: Use the ESC button or set the rotary switch to another position to cancel the temporary temperature change function. Sauter Components 7001029003 T8...
Then, this controller sends its system time to the device bus once every 24 hours. This time is adopted by the other controllers. Regardless of the setting of communication parameter CP09, if the time is adjusted on one of the interconnected controllers, it will be adopted by the others. Sauter Components 7001029003 T8...
