Forward-acting (heating-loop) or reverse-acting (cooling-loop) * PID-output signal (slow PWM, T=12.5 sec) present at **S3 output** for connection to a Solid-State Relay (SSR) * Standard thermostat functionality available when PID-controller is disabled (**TS** parameter set to 0) * Second temperature probe functionality selectable with **Pb2** parameter. If **Pb2** is set to 0, no second temperature probe is connected. ..+ With **Pb2** set to 1, the second temperature probe should measure the outside temperature. Used in thermostat control. ..+ With **Pb** set to 2, the second temperature probe should measure the compressor temperature of a refrigerator. Used in refrigerator mode to also control the compressor fan. * Up to 4 profiles with up to 6 setpoints (6 profiles with 10 setpoints if the STM8S003F3 is replaced with a STM8S103FS µC) * Each setpoint can be held for 1-999 hours (i.e. up to ~41 days) or 1-999 minutes (i.e. up to ~16 hours) * Approximative ramping * Somewhat intuitive menus for configuring * Separate delay settings for cooling and heating * Configurable hysteresis (allowable temp swing) from 0.0 to 2.5°C or 0.0 to 5.0°F * User definable alarm when temperature is out of or within range * Easy displaying of setpoint, thermostat/PID-mode, actual temperature (default), 2nd temperature and PID-output (%) # Using the STC-1000p-STM8 firmware ## Navigation and menus By default the current temperature is displayed in °C or °F on the display, depending on the **CF** parameter. Pressing the 'S' button enters the menu. Pressing button 'Up' and 'Down' scrolls through the menu items. Button 'S' selects and 'Power' button steps back or cancels current selection. The menu is divided in two steps. When first pressing 'S', the following choices are presented: |Menu item|Description| |--------|-------| |Pr0|Set parameters for profile 0| |Pr1|Set parameters for profile 1| |Pr2|Set parameters for profile 2| |Pr3|Set parameters for profile 3| |Pr4|Set parameters for profile 4 (STM8S103F3 only)| |Pr5|Set parameters for profile 5 (STM8S103F3 only)| |Set|Settings menu| *Table 2: Menu items* Selecting one of the profiles enters the submenu for that profile. Pr0-3 submenus have the following items: |Sub menu item|Description|Values| |--------|-------|-------| |SP0|Set setpoint 0|-40.0 to 140͒°C or -40.0 to 250°F| |dh0|Set duration 0|0 to 999 hours| |...|Set setpoint/duration x|...| |dh4 (dh8 with STM8S103F3)|Set duration 4 (8)|0 to 999 hours| |SP5 (SP9 with STM8S103FS)|Set setpoint 5 (9)|-40.0 to 140°C or -40.0 to 250°F| *Table 3: Profile sub-menu items* You can change all the setpoints and durations associated with that profile from here. When running the programmed profile, *SP0* will be the initial setpoint, it will be held for *dh0* hours (unless ramping is used). After that *SP1* will be used as setpoint for dh1 hours. The profile will stop running when a duration (*dh*) of 0 hours OR last step is reached (consider *dh5* implicitly 0). When the profile has ended, STC-1000p-STM8 will automatically switch to thermostat mode with the last reached setpoint. (So I guess you could also consider a *dh* value of 0 as infinite hours). The settings menu has the following items: |Sub menu item|Description|Values| |---|---|---| |SP|Set setpoint|-40 to 140°C or -40 to 250°F| |hy|Set hysteresis|0.0 to 5.0°C or 0.0 to 10.0°F| |hy2|Set hysteresis for 2nd temp probe|0.0 to 25.0°C or 0.0 to 50.0°F| |tc|Set temperature correction|-5.0 to 5.0°C or -10.0 to 10.0°F| |tc2|Set temperature correction for 2nd temp probe|-5.0 to 5.0°C or -10.0 to 10.0°F| |SA|Setpoint alarm|0 = off, -40 to 40°C or -80 to 80°F| |St|Set current profile step|0 to 4 (8)| |dh|Set current profile duration|0 to 999 hours| |cd|Set cooling delay|0 to 60 minutes| |hd|Set heating delay|0 to 60 minutes| |rP|Ramping|0 = off, 1 = on| |cF|Celsius or Fahrenheit display|0 = Celsius, 1 = Fahrenheit| |Pb2|Enable second temp probe for use in thermostat control|0 = off, 1 = on, 2 = refrigerator mode with compressor fan control| |HrS|Select Hours or Minutes time-base|0 = minutes, 1 = hours| |Hc|Kc parameter for PID-controller in %/°C|-9999 to 9999| |Ti|Ti parameter for PID-controller in seconds|0 to 9999| |Td|Td parameter for PID-controller in seconds|0 to 9999| |Ts|Ts parameter for PID-controller in seconds|0 to 9999| |rn|Set run mode|Pr0 to Pr5 and th| *Table 4: Settings sub-menu items* **Setpoint**, well... The desired temperature to keep. The way STC-1000p-STM8 firmware works, setpoint is *always* the value the thermostat or the PID-controller strives towards, even when running a profile. What the profile does is simply setting the setpoint at given times. **Hysteresis**: This parameter is used when the thermostat controls the temperature (**Ts** is set to 0). This parameter then controls the allowable temperature range around the setpoint where the thermostat will not change state. For example, if temperature is greater than setpoint + hysteresis AND the time passed since last cooling cycle is greater than cooling delay, then cooling relay will be engaged. Once the temperature reaches setpoint again, cooling relay will be disengaged. **Hysteresis 2**, This parameter is used when the thermostat controls the temperature (**Ts** is set to 0). Futhermore if **Pb2** is set to 1, temperature probe 2 should measure the environmental temperature. Now the allowable temperature range around the setpoint for temperature probe 2 is controlled. For example, if temperature 2 is less than **SP - hy2**, the cooling relay will cut out even if **SP - hy** has not been reached for temperature. Also, cooling will not be allowed again, until temperature 2 exceeds **SP - 0.5 \* hy2** (that is, it has regained at least half the hysteresis).<br> If **Pb2** is set to 2, then this parameter controls the compressor fan (which should be connected to the heater output). For example: if **Hysteresis 2** is set to 100 E-1 °C, the compressor fan is switched on when probe 2 temperature exceeds 35 °C (30 + **Hysteresis 2**/2) and switched off when probe 2 temperature is below 25 °C (30 - **Hysteresis 2**/2). Temperature probe 2 should in this case be attached to one of the compressor output pipes (which should get hot when the compressor is turned on). **Temperature correction**, will be added to the temperature sensor, this allows the user to calibrate the temperature reading. It is best to calibrate with a precision resistor of 10 k Ohms (1% tolerance). Replace the temperature sensor with such a resistor, let the STC-1000p-STM8 run for at-least half an hour and adjust this parameter such that the temperature display is set to 25.0 °C. **Temperature correction 2**, same as *temperature correction*, but for the second temperature probe. If you remove the existing 2-pin terminal-block and replace it with a 5-pin terminal-block (see below for details), you can connect a second temperature sensor. The 1st temperature sensor is connected to pins 2 and 3 (seen from the left), the 2nd temperature sensor can now be connected between 1 and 2. Enable this 2nd sensor with the **Pb2** parameter. **Setpoint alarm**, if setpoint alarm is greater than 0.0, then the alarm will sound once temperature differs from *SP* by more than *SA* degrees (this can be useful to warn against ma
