Operating the Control The ZG 215VN can be used at choice for the control of an air-handling system’s constant discharge temperature (left- hand system diagram) or a floor heating’s constant flow tempe - rature (right-hand system diagram). The VF/LF temperature sensors monitor constantly the actual va- lues and transmit these values to theZG control unit.

Operating Mode Selector manu The control unit is deactivated (the timer runs). The mixing valve can be set manually (by hand). The pump is switched on. auto Recommended setting for higher energy saving: automatic change between day and reduced mode according to the timer with night switch-off.
LED’s Both LED’s light up: ”neutral“ – mixing valve stops only red LED lights up: ”hotter“ – mixing valve opens only green LED lights up: ”colder“ – mixing valve closes In the manu settings of the operating mode selector there is no LED display.
Putting into service Set the timer with the current time to auto Set the operating mode selector The remaining basic factory settings are printed under on the control unit. Timer for reduced mode With the aid of the timer, the room temperature during idle periods can be reduced automatically to save on operating costs.
Changing the program Factory settings: pin 6:00, blue pin 22:00. Pull out the trip pin and insert it again at the desired switch-on time. Push in the trip pins until they reach the stop! Owing to the different lengths, the trip pins must always be inser - ted in a red/blue alternate ordere.
Example: Desired time program Normal temperature: 6:00 h to 8:00 h and 16:00 h to 22:00 h Night decrease: 22:00 h to 6:00 h Day decrease: 8:00 h to 16:00 h Position of the trip pins 6:00 h – Start day mode (normal temperature) blue pin 8:00 h –...
Optimization of the Settings The ZG 215VN control unit is a constant temperature controller. The desired temperature, e. g. the supply temperature of an air-handling system or the flow temperature of a heating system can be set on the setting knobs of the controller.
Example (with TW 23) è 20 Setting on the setting knob P2 è 50 Setting on the TW 23’s selector knob è -20 Setting on the setting knob Both settings give target values of 50 °C in the day and of 30 °C at night.
Remote Control TF 22 (optional) Setting the Room Temperature On setting knob P2 the setting of the room temperature can be fine tuned. The setting without the remote control is always 20 °C. With the respective remote control another setvalue may be tuned. The scale on the selector is divided from -7 to +7 and corresponds more or less to the variation in degrees.
Examples TF 22 TW 23A Selector knob P2 +1 +2 20 21 22 23 Room temp. [°C] 20 21 22 20 21 22 23 If no temperature selector is available, the desired room tempera - ture can be set only on the setting knob of the control unit.
Troubleshooting Checklist Is the heat generator at the required temperature? è Read the heat generator’s thermometer. Is the burner ready? Is the burner failure lamp on? è If necessary, press the reset button. Was the temperature selector set by mistake? Setting of the selector knob P2 Check the setting of the control unit.
Manual mode (fig. on the left) In case of the breakdown of the heating mode regulation, you can proceed temporarily as follows: on manu . 1. Set the operating mode selector 2. Open the mixing valve by hand until the desired flow and room temperatures are reached.
