lindab | we simplify construction Control equipment Regula Combi 1.5 Display handling and indications Regula Combi has an Occupancy button, as well as an INCREASE button and a DECREASE button to increase and decrease the set point. Example: The control setpoint is 22°C and the added displacement is +1.5°C. This means that the value 23.5°C will be shown in the display. ”HEAT” or ”COOL” will flash depending on which of the setpoint values is the control setpoint when you enter the set point menu, i.e. depending on which set point you are changing. The displacement is added to both the heating and cooling set point. › OFF STANDBY COOL SERVICE HEAT Occupancy button INCREASE button DECREASE button Bypass indicator (Forced ventilation) Changeable value Setpoint Room temperature ≈ › OFF STANDBY COOL SERVICE HEAT Occupied indicator Current room temperature in ºC to one decimal point STANDBY: Standby indicator COOL-HEAT: shows if the OFF: Unoccupied (the temperature is shown) unit controls according to the heating or cooling setpoint. or OFF indication (only OFF is shown). SERVICE: Is shown when parameters are set, flashes when there is something wrong with the controller. There are numerous possibilities of what to be shown in the display (with parameter 42), also at setpoint adjustment (with parameter 74). User limitations of the buttons can be set with parameter 43, 44, 108 and 109. Note: changing parameter 109 will block re-entry of parameter menu via display. Parameter access will then only be possible using Regio Tool. Parameter menu It is possible to set different parameter values in the parame- ter menu. The parameter menu is accessed by simultaneous- ly holding the INCREASE and DECREASE buttons depressed for about 5 seconds and then pressing the INCREASE button down for about 5 seconds. The Service indication will be dis- played. Press the INCREASE bottom twice. First the display will show the parameter number 0 (which chooses program). Scroll between parameters by using the INCREASE and DECREASE buttons. Press the Occupancy button to select the desired parameter. The parameter num- ber will be replaced by the parameter value. The value can be changed using the INCREASE and DECREASE buttons. If a button is held depressed the value will start scrolling, first slowly and then with increasing speed in 3 – 4 steps with 2 – 3 seconds between steps. To retrieve the original value, i.e. the value before change, press the INCREASE and DECREASE buttons at the same time. The original value is shown on the display. To acknowledge and store a set parameter value, press the Occupancy button again, the display then returns to showing the parameter number. After a certain time, about 1 minute, or when the INCREASE and DECREASE buttons are pressed at the same time while in the menu, the display returns to the normal view. Exit is shown on the display after the last parameter. The param- eter menu is exited by pressing the Occupancy button while in Exit. Pressing INCREASE goes to the first parameter and pressing DECREASE goes to the last parameter. In the Parameter list the numbers of selectable parameters will vary depending on which program is activated. The defaults for all programs are shown in the parameter list. Not all parameters are selectable in all programs. Connecting actuators The maximum number of actuators that can be connected to the digital output (ON/OFF) is 10 for cooling and heating, respectively. When more than 4 on/off actuators for cooling or heating are connected, terminal blocks 10 and 20 must be connected with a cable because the Regula Combi print card can not handle the output power for more than 4 on/ off actuators. 4 Lindab reserves the right to make changes without prior notice 2021-04-27
