PIR ( Movement sensor) input for occupancy detection (see page 11) The SRC-131 is powered by 24VAC and requires the 24VAC active and neutral to be connected to the “R” (active) and “C” (Neutral) terminals for the SRC-131 to function. The 24VAC applied to the SRC-131 “R”... -
Page 7: Outputs
As the SRC-131 is fitted with both relays as well as 0-10V outputs to control HVAC systems there may be some slight disparity between the thermostat display and the 0-10V outputs actions. The SRC-131 displays the relay actions more than the actions of the 0-10V outputs on the LCD. -

Modbus object data can be found later on this manual. The SRC-131 uses a high powered Maxim chipset that will “theoretically” permit the connection of up to 255 devices on a single Modbus node. RF noises and other interferences will reduce the real world permitted connections to a maximum of 200 in most cases. -
Page 13: Installer Options Menu
Installer Options Menu The SRC-131 has an impressive list of options that can be installer selected. These options tune the controller’s performance as well as set energy conservation settings. This menu is deliberately hidden and difficult to enter to discourage unauthorised tampering. -
