[Configuration](https://knowledgebase.grenton.com/en/manuals?hsLang=en#configuration) # Control of a heating zone with more than one actuator When a single heating zone includes more than one actuator on the manifold, you can still control all of them using a single virtual `Thermostat` object. Simultaneous control of multiple output objects can be configured as follows: 1. Create a virtual `Thermostat` object setting the temperature sensor located in the given heating zone as the temperature source. Assign one actuator from the selected heating zone as the output. ![](https://knowledgebase.grenton.com/hs-fs/hubfs/1-png-Mar-05-2026-10-07-52-8749-AM.png?width=409&height=383&name=1-png-Mar-05-2026-10-07-52-8749-AM.png) 2. After creating the `Thermostat`, open its `Events` tab. 3. Assign the `SwitchOn` method of the remaining actuators in the group to the `OnOutOn` event. ![](https://knowledgebase.grenton.com/hs-fs/hubfs/2-png-Mar-05-2026-10-13-47-7657-AM.png?width=670&height=490&name=2-png-Mar-05-2026-10-13-47-7657-AM.png) 4. Assign the `SwitchOff` method of the remaining actuators in the group to the `OnOutOff` event. ![](https://knowledgebase.grenton.com/hs-fs/hubfs/3-png-4.png?width=670&height=500&name=3-png-4.png) 5. Upload the configuration to the CLU. 6. If the heating zone contains more than five actuators, create a script and assign it to the `OnOutOn` event instead of adding individual method calls. ![](https://knowledgebase.grenton.com/hs-fs/hubfs/4-png-Mar-16-2026-08-07-40-2083-AM.png?width=670&height=151&name=4-png-Mar-16-2026-08-07-40-2083-AM.png) `CLU->x201000597_DOUT_02->SwitchOn(0)` `CLU->x201000597_DOUT_03->SwitchOn(0)` `CLU->x201000597_DOUT_04->SwitchOn(0)` `CLU->x201000921_DOUT_01->SwitchOn(0)` `CLU->x201000921_DOUT_02->SwitchOn(0)` `CLU->x201000921_DOUT_03->SwitchOn(0)` 7.
