Regulator firmware and software HC downloader

The HC downloader software runs on Windows 7 and later. Since version 2.0 we provide only 64-bit versions of the HC downloader software, up to version 1.0 they are 32-bit.

Please always update BOTH software and firmware for your device!

Newest version (March 2024):
Added: Valve control indicator (Heating circuits tab).
Added: Min. source temp. for valve reinitialization (Heating circuits tab).
Added: Output labels to the Output test panel (Settings tab).
Added: OPTIONS request type to the device HTTP server.
Added: CORS headers to allow cross origin HTTP requests (as needed by the mobile app).
Added: S-CONNECT: Implemented protocol version 2 - new device types, manual station pairing, etc. (S-Connect tab).
Added: S-CONNECT: In the device mapping table, a visual indication of available devices for each device type has been added (S-Connect tab).
Modified: Write limits for parameter Cool down limit for heat pumps (Others tab).
Modified: Further optimized web interface for shorter loading time and smaller FLASH footprint.
Fixed: Behavior of the mixing valve, the valve might not fully close after its reinitialization (Heating circuits tab).
Fixed: Low heat source temperature indicator might work incorrectly (Heating circuits tab).
Fixed: Control block values not cleared when control block has been deactivated.
Fixed: System reset after configuration write did not work correctly.
Fixed: Vertical scaling issues of the realtime charts (Realtime Chart tab).
Fixed: S-CONNECT: Remote output types stayed indeterminate even after S-CONNECT was turned off and on again.
Fixed: S-CONNECT: Users could not map one input source device to different destination devices (eg. T1-RT1, T1-M1).
Fixed: S-CONNECT: Users could map two or more source devices to the same destination device (eg. T1-RT1, M1-RT1).

Modified: Limits for temperature differences in differential controllers (T.diff. to switch on now 4 to 30°C, T.diff. to switch off now 0°C to T.diff. to switch on - 1°C).
Fixed: TEST buttons and "Search for digital temp. sensors" button did not work with higher HTTP security disabled (this was bug in v.2.0).
Fixed: T11 did not show up in real time chart as temperature but as percentage (this was bug in v.2.0).
Fixed: Bug with incorrect white space evaluation in the HTTP protocol.
