Telereef Controller - User Manual V.140313
!
• Temperature controller for chiller and heater
!
Each temperature sensor which connected to Telereef Controller can be set up to
controls it's own cooling and heating devices, the way to set up is defining what
temperature to turn on the device and what temperature to turn off the device.
For example, if the target water temperature is 26°C, the fluctuate allowance is +/- 0.2°C,
turn on temperature of cooling device will be 26.2°C, turn off temperature of cooling
device will be 26°C and turn on temperature of heating device will be 25.8°C, turn off
temperature of heating device will be 26°C
If T1 Sensor will be use and Socket 2 is connecting to cooling device and Socket 3 is
connecting to heating device, go to Setup page, scroll down to Temperature Settings,
push Edit button and input the following settings
Make sure the temperature ranges of cooling device and heating device are not overlap
each other. In case the on and off is too often, consider to use a bigger fluctuate
allowance (eg. +/- 0.3 or +/- 0.4)
!
You can also use Temperature Setting Wizard to setup all the ranges for you, simply
push “Wizard” button on Temperature Settings page, input the target temperature of each
Temperature Sensor, the system will calculates the Cooling range, Heating range as well
as Alert range according to d/- 0.2°C fluctuation.
!
On chiller and heater usually have their own temperature controllers, make sure set the
temperature on them to one or two degree celsius more (or less) than the target
temperature set on Telereef Controller. If target temperature on Telereef Controller is
26°C, set chiller’s own temperature to 28°C and heater’s own temperature to 24°C.
Because this temperature range is larger than the temperature range that Telereef
Controller activates the chiller and heater, so it will not affect the normal operation of
Telereef Controller, it also works as secondary emergency cut off in case the relay
module is out of order or wrong setting is applied on Telereef Controller.

• pH controller
!
The procedure used to setup pH controller is similar as setup temperature controller. For
example, controlling CO2 dosage in a calcium reactor, target internal pH value is 6.5,
fluctuate allowance is +/- 0.2, Socket 4 connected to the CO2 valve, go to Setup page,
